I want a tablet, so I'm gonna get one off of Ebay. Does anyone know if this is good for drawing?

I guess you could say I'm interested in drawing Anime and Manga like drawings, but I have other styles.
I also want to know if it is touch sensitive and good for coloring and stuff? xD;.

Thanks in advance
+can I use it in photoshop CS4 or Paint Tool SAI?

I'm also worried about that XD;. I'm pretty sure I can but my dad is being a cheapoh sneaky face (lol) and is trying not to get me it. XD
