So sorry if this should have been found via searches (I tried, for hours!), 
but I'm exhausted trying to collate these answers into a simple form I can 
comprehend.

*Questions that relate to WeeWX usage*

Do these models allow for completely offline (no Internet, just intranet 
(home) access) data extraction for processing by weewx? I have read about 
the weewx-interceptor <https://github.com/matthewwall/weewx-interceptor> 
and the listen mode. These two units are not explicitly mentioned 
(including on the hardware guide <http://weewx.com/docs/hardware.htm> or 
supported 
hardware <http://weewx.com/hardware.html> pages).

Does the SD card for the WS-2000 do any continuous collection? 
If my computer is down, is any data maintained in the console that can be 
retrieved later? 
Is it "automatic" the way the Davis data logger would have the last 44 
hours of data (every minute collection) and my computer would get 
everything missed to catch up and resume regular collection?
Or do I have to be aware of it, trigger the export on the console, and move 
the SD card elsewhere to import it?
I see it has an archive mode, but I don't understand if that is merely for 
console display or if it helps achieve what I'm asking.

I have years of data in an MySQL database from a Davis 6152. How cleanly 
does the data from these go into that database or should I start a new one?

Does the low battery information get exported with the weather data?

*Questions that are not related to WeeWX*

My mount is a 10' mast and my current station is mid-pole. These seem only 
designed to go on top of a pole (what about something higher than the 
station for lightning strikes?), do I need to get some side mount extension 
for these?
The Davis has the u-bolts opposing each other for a stable mounting and 
these are oriented facing the same direction. Does that affect the quality 
of attachment?
How easy is it to clean out the rain gauge?
Is the bird spike worth getting?
Why not position/bend the spikes prior to installation?

Side question: how much of an "issue" is it that the integrated temperature 
sensor is 5' above the apex of a two story house instead of 5' above ground?

*Background*

I moved into a new house and the wind was significantly more than I was 
used to. That made me curious about its speed and I bought a cheap LaCrosse 
WeatherChannel unit from Best Buy. 

That interested me enough to look into getting something better and I got a 
Davis 6152C for $333 from Ambient Weather (.com) plus the 6510SER for 
another $139 (+tax + shipping $488). That was May 2007.

The mount is a 10' pole on the apex of a two story house with the station 
about 5' up so I can reach it and lightning strikes would be several feet 
above. It was (unfortunately, not currently) grounded to a 6' ground spike 
put in by the installer to protect his equipment on it (long-range radio 
for Internet access which has been gone for a decade or so).

In January 2008, a winter electrical storm strike took out the station all 
the way to the console (but thankfully not the COM port on the WinXP box). 
Nearly $500 taken out, what would reduce that happening again?

In March 2008 I spent more money to get a 6152 ($400), a new 6510SER 
($139), and a 6316 ($139). That's $700 spent just to get conditions at my 
house versus a web page (or app) showing me a 15+ minutes old, 10ยบ off 
reading from elsewhere.

That's a lot of money, but I liked it and have been proud of it. Other than 
a repair to the rain gauge (soldering a complimentary new resistor for the 
reed switch), it's been working pretty well. Although, the solar panel is 
rather clouded over and new batteries only last one year (remember to put a 
fresh one in by mid-December!).

Now the anemometer isn't working. I've been wishing for a new station, so I 
checked out the prices. Same site I bought the first two (and the maker of 
the models I'm asking about) is now selling the 6152 for 32% more than 
before at $527. Most electronics have dropped in price and increased in 
functionality and features, this is the same old model for 32% more?! No 
thanks. (Yes, there are alternative sellers, but I am soured on the 
increase which is also reflected on the Davis website.) I think that if the 
price was at least the same as before or less, I wouldn't have shopped 
around much. Oh well.

I am impressed that there are so many less expensive alternatives now that 
seem to do a decent job. That really wasn't the case back in 2007/2008. The 
cheap ones were cheap in every sense of it. So, in searching I have 
narrowed it down to these two models. I am very interested if someone has 
another recommendation, though.
