no, I use an aiptek. my opinion is that mine is probably a low-end one, but still I love it, so with a wacom it muct be just great.
for foxfire specifically, I dunno if it would be good.
I use mine for everything, you'd use yours for coloring, I suppose. that would change the style of the thing.
really, you have to try by yourself first. if you're like me and you don't have a friend who owns one, well, you'll have to be ready to pay a lot for something you're not sure you'll like. in my case I wasn't disapointed ( even tho at the begining it was highly disturbing, and not that easy

).
it's really your call.
