Just went to tigerdirect.com and typed in 'all in one pc' and got lots of hits - some touch, nontouch. Lots of brands - I use 400 dollar Averatec with 18" screens and can mount on wall with XP home, but for under 1,000 you can get lots of different machines. Take a look.
P.S. I have no financial incentive for Tigerdirect other than I send lots of my money to them.
