I want to buy a used drawing tablet, where is a good place to do that?

It's just about the smaller drawing area that the S size wacoms have. You wouldn't have much space to draw on and you might develop some bad habits since you'd be drawing mostly from your wrist and would end up with drawing like that on other mediums.

If you'd like to see if it's something that would bother you, just find the dimensions of the various sizes of the drawing tablets and line them out on a surface like paper. Try and imagine drawing on that surface and see what you think. The L sizes are about the size of a piece of A3 sketchbook. I personally used the M size for many years and it served me more than well, so take it how you will.
