I have a few questions regarding drawing tablets. This is mainly because I am thinking about buying one, but dont want to waist the money if I get a bad one or something.

Would you recommend a tablet for mapping, Why?
What is a cheep yet still good tablet?
How long dose it take to learn how to use the tablet concretely?
What are problems you find when using a tablet?
If I get a tablet, how long will it take for me to want to light it on fire and throw it off a cliff?

If you guys have any other suggestions about tablets let me know, I am really interested in them, but seeing how expensive they are I want to know what good tablets are.
