I would recommend DD-WRT for the firmware if you are gonna go Linksys.
You will get probably the same performance out the Linksys stuff with
this firmware as you would with the high-end / pricey Cisco stuff. You
will find that it is hard to find Linksys routers / access point that
support 3rd party firmwares though. I believe there is a WRT-54GL or
something out there now that is specifically designed to run "Linux" as
it's firmware. I use Buffalo routers at home, which is the new
recommendation of the DD-WRT guys these days. They are cheap too. I do
however find the Linksys products seem to have a stronger signal. So you
would definitely want to amp the Buffalo stuff.

Anyway, if money is an object I would go with WRT54G linksys boxes, NOT
running Linksys code. Why? For distances this great I would highly
reccomend amplification. In order to run amps without rediculious
noise you
need to drop the input power on your AP going into the amp. I've
found 20
mw of power works best.
Being as this is a point-to-point link you can raise the gain on the
antennas and the amps a bit to. Here are your limits:
Total Amp Max gain EIRP in watts
*30dBm 1W 6dBi 3.98
29dBm 800mW 9dBi 6.35
28dBm 630mW 12dBi 10.14
27dBm 500mW 15dBi 15.81
26dBm 398mW 18dBi 25.23
25dBm 316mW 21dBi 40.28
24dBm 250mW 24dBi 62.79
23dBm 200mW 27dBi 100.2
So, looking at this we have a couple options. I'd go with Yagi
antennas or
dishes. Personally I would only mess with 500 mw or 1 watt amps, too
much
freakiness on the adjustable amps.
Use LMR400 antenna cables. The other stuff has too high loss. And mount
the amp as close to the antenna as possible.
Personally I'd go with Antennex Yagis, they are weatherproof and sealed.
Nice. At 14.6 dBi gain you can still go with a 500 mw amp and you'll be
just under max power. Anything more then 100 yards I'd consider going
with
dishes, but at this power level you should be ok.
Use WPA between the devices too (keep the prying eyes out). If you get
adventerous try afterburner mode on the wrts. I've never tried it, but I
can't see why not.
Anyway, those are my suggestions.

I've done this before, not locally though. We used Cisco 350 bridges.
Worked great, except for when it got snowy/icey which I don't think will
be a problem here. We had multiple sites with yagi antennas. At the
center we had an omni. We had a 3 mile radius. The extreme edges got
kinda sketchy, but 100 yards should work fine and be stable.
I would recommend the Cisco stuff, or even the Linksys ( which is now
owned by Cisco ) stuff if this is tmp / on a budget.
How is your line of site ? This is VERY important for long distance
hauls.
