I bought a Wacom tablet after giving myself carpal tunnel making my first PS map, and I absolutely love it! I now sketch, draw, map, etc. etc. etc. with it. So much more convenient.

I have not had really any technical difficulties--but I've only had the tablet for a few months now, so who knows about the future.

I did cheap out & bu the smallest, least sensitive tablet, & I have not been disappointed. It cost under $100 at Best Buy, and I really enjoy it. I say go for it if you can afford it. A neat toy!
