lithron's Journal: Windows Thin Clients... opinions wanted

At work we're looking into selling Windows based thin client solutions to our customers. All we need it to run is Acrobat Reader v5 or higher, a driver for the USB/HSB signature pads we use, and a custom graphical Windows telnet client.

Does anyone have any suggestions on brands of thin clients to check out? We already inspected one IGEL solution and I'm testing another IGEL solution today. However, I would really like a recommendation from someone that actually deploys thin clients.

Hardware specs of what we need:
100 to 150 megs of hard drive space.
256 megs of ram.
1Ghz or faster x86 processor
10/100 Ethernet access and DHCP support is a requirement.
At least 4 USB connections.
at least 1 parallel port

So.. anyone have any advice or suggestions?

TIA.
