OT: used / refurb voip phones?

[Shacolby Jackson <shacolby () bluejeansnet com>]

A little off topic but anyone have any recommendations for vendors selling
used voip handsets, especially Polycom? Looking for some IP335 or better.

There are only a couple used gear resellers I trust and none seem to carry
Polycom, only Cisco and even those only seem to have low end handsets.
