Buying a Bamboo Fun Touchpad & Pen

Hey guys. I'm thinking of buying one like the title says, but I want to know some things before I go and spend 200 dollars.

So, the main reason I want to buy this is for drawing and whatnot, but I really suck. I want to know if I draw (or attempt to draw) a shape but fuck it up, if I can fix it with the pen tool, like drag the line and stuff.

I also want to know how sensitive it is, and if it has a bad lagtime or anything. Any answers to this will be appreciated.

I don't really see why you can't use the pen tool, I have a Bamboo fun (not the newer one) and I use it for just about everything pen, anchors, brush, lasso, etc. Shoot as for sensitivity goes I'm unsure whether they increased it with the this newer Bamboo they have, but I'm almost positive that they haven't change the pressure levels. (Lol I can't find my Bamboo tech specs so don't hold me to it)
As for lag time, I have never experienced any sort of lag with my Bamboo. I use my Bamboo about everyday XD, mostly for editing H-M and minor drawing. (I kinda find it difficult to free hand draw on the Bamboo, partly because on paper I spin it around drawing in an angular way and I can't do that with a Bamboo lol but thats just me and my retarded drawing style) If your really serious/dedicated about drawing with the Bamboo I would really recommend you paying the extra $30 to get the Intous. (I'd get one, but I'm saving for a Cintiq XD)
Any who I hoped I helped! :)

Cool, thanks!
