If the Computer Pro Show comes to your town or city try to pick one up there. I picked up my HP P1100 series 21" that had been refurbished and came with a warranty for 2 or 3 years under $150.00
When I went to HP website to find the drivers for it, I found out it was an IT Professional series monitor, has all them extra hook ups in the back, and it's a flat screen and excellent picture. Looks like brand new as well.
