I think you can get one starting at about 150 in Walmart...but the screen is kinda small. The more you pay, the better screen, graphics, etc you get. I would say around 300-400 would get you a really good one. Just a guess though. We got one for about 200 for my dad while he was traveling for chemo treatments. It works pretty well, but after only a year, there is a short in the power cord...
