I have a few resellers that love HP Thin Clients, and swear that they are faster than other manufacturer's to power on and connect.  The others that I've used a lot are Comupter Labs (CLI) and Wyse.

We've tested a t5135 (HP Thin OS) and 6720t (XPe) with VDM, Leostream, and Provisionnetworks VAS.  We've only had much success with the 6720, the 5135 should worth with VAS and Leostream but it acts buggy and doesnt always connect. 

We also bought a t5735 (Debian Linux) just to try it out, out of the box it doesn't have software for connecting to any of the connection brokers we've tried.

All of them work great if you aren't planning on using a connection broker.
