Lemme ask around for you, I may be able to find something. ^^

I can tell you off the bat that Wacom is a good company, but I'm not sure how inexpensive they are.

i can help ya with that! the first USB tablet i got was under $100. ill leave you some links here. if you have any other questions, feel free to contact me! just keep in mind to check the size of the tablet along with the pressure sensitivity. the higher, the better!

i hope i helped!! like i said, lemme know if you need anything else!

if you can find Wacom for cheaper, that brand is fantastic but you will probably only find the smaller ones. i dunno what size workin space you are looking for.

Oh thank you so much! I'll look for Wacom then ! Both of you two have been a big help ^^

No worries! hope you find something good!
