I was unsure where to post this. I'm quite new here.

I'm looking to purchase a tablet with a work area of at least 6 x 8 inches. Coloring in photoshop is the biggest pain, with a mouse. Does anyone have any suggestions for places to purchase cheaper, used tablets? I am on a very tight budget for the time being. Doing some commissions more efficiently with a tablet will help me work on my debt.

Any help would be GREALY appreciated. I'm not looking for perfection. I just need something that works.
