God, give my a tablet!

Grahgr!  I am very irritated due to the fact that have a bazillion pics drawn and laying lazily about my room .. and couch .. and upstairs hallway ... and backpack ... and in a pile that fills two-thirds of my locker (the other third being owned by various caffeine based treats to keep me awake during the school day).

And of course, there are the 7 commissions that I need to finish and post.

However, my annoyance comes from the fact that I wish to use my wonderful-tastic Open Canvas program that I just procured ... but I don't have a graphics tablet.  My mouse sucks!  I would post so much more if I could get my hands on one.  Any suggestions?  I will give an absoltutily free commish to anyone who can give me good advice.  I is desperate!
