asterisk users - Jun 2007 - wifi sip phone real-world experiences?

I've tested a few different wifi SIP phones for office/factory use, and 
generally have been underwhelmed.  Before I grab another few and test, I'd 
like to ask around here about the candidates.

My requirements are relatively simple:
- WEP/PSK should be supported WITHOUT dragging the phone down
- roaming between access points without dropping the call
- decent set of ringers, not the garbage that cell phones use now
- vibrate, ring, ring&vibe (increasing volume a bonus)
- transfer, hold, display caller ID
- mass deployment (similar to polycom?) TFTP/FTP/HTTP config
- decent, but not enormous battery life
- replaceable batteries

What's not important:
- NAT passthrough
- colour screen
- MIDI ring tones

Bonus features:
- programmable soft buttons
- bluetooth

Currently I'm looking at the WIP300/330 and if I can find a source, the 
C&W/Hitachi wifi phone.  I've tried some of the UTStarCom phones,
Pulver's
WiSIP and another I can't think off offhand.

Is there anything out there that anyone else has been reasonably happy with?

Did you look at this one?

No frills, specs look good, price seems excellent!

We're thinking of buying a couple for communication between our IT team
members across 5 floors in 2 buildings.

If you've tried it I'd be interested to hear you review.

Cheers

Thank you for posting; tell me, with these Kirk phones, is there any kind of 
phone book or contact list for speed dials that I can set up?  Is it a 
central list, or does each phone have their own?
