We support scanners from Grabba, Symbol, and Socket in all of our products.
On the PalmOs side almost all of our users have a Grabba T-series unit and
they work great and almost never generate support issues.

On the PocketPC side it's a different story.  Grabba has finally release a
unit that works with some HP units, but not all.  They current have nothing
for the Dell Axim units.  Our users tend to be cost sensitive so they buy
from Dell because they're less expensive.  However when they want a scanning
solution, they're stuck.  So, imagine our excitement when Socket introduced
the CHS scanner (yes this does tie into the thread of the discussion)

Unfortunately it didn't work out so well.  I made the necessary changes to
the software and tested it outside scanning VINs.  The scanner itself worked
fine.  The next week a user who had purchased one took it with him to an
auto auction.  Big problems.  The device would go to sleep before the
scanner went to sleep.  The user would wake up the device, try to scan, and
it wouldn't work.  The only way to get it going again was to turn off the
scanner, reset the device, and then let the scanner pair with the device
again.

I spent a few days trying to resolve the problem with some help from Socket.
In the end the only way to insure that it would work would be to prevent the
device from going into suspend mode.  The fundamental problem was that when
the BT stack was suspended, it didn't communicate that with the device that
was paired with it.  Apparently different BT stacks handle the situation
differently so I'm not sure what would happen with a Palm device, but your
first two items of concern are valid.  We never got further than one user so
I can't speak to items 3 and 4.

One downside to the Grabba is that if there is a camera on the backside of
the device, it is covered up.  So a two handed solution may be better if the
camera is important.  The CHS does come with a lanyard.

Our users need a class 2 laser or an imager so the cost is about the same.

Have you tried using BT scanners in a production environment?  I have the
following concerns, which may be unfounded assumptions, but make me hesitant
it
would be viable in the environment where I'd most like to use it.  

That environment is a sales order process where there could be upwards of 40
people all working within BT Class 1 range of each other and where the time
between scans may be enough to have the pda auto-off.

Concerns:

 1) Once in the trusted list etc, how much delay is there while pairing
after
        first turning the pda back on?  If the pda auto-powers off from 
        inactivity, it must pair again before the next use, right?

 2) If the pda has auto-off'd, then just trigerring a scan on the CHS will
        not awake the pda and let it act on the barcode.  You must turn the
        pda back on, let it re-pair, then continue.  Or so I'd suspect.

 3) If multiple people attempt discovery at the same time, is there a risk
        one will try to pair with the wrong scanner?

 4) Can 40+ scanners co-exist peacefully within range of each other?

 5) Usage becomes a two-handed operation: one to hold the pda and
        the other to hold the BT scanner.

 6) It isn't significantly cheaper than direct attach scanners, such as the
        Grabba T series (which has models for the Treo 650 and others)

Truthfully, what I really miss is the Symbol CSM150 springboard in a Visor
Prism.  For price/performance, it was a pretty unbeatable combination.  And
Symbol hasn't come out with any new SPTxxxx models, only Pocket PC based
scanners.
