[doesn't have to be new]

Hey new member here.

My brother and I were talking about buying into River Ranch as I came across it a couple days ago on flebay.  He has some Honda 4x4 400+cc shaft driven ATV that he rides a bunch and I was thinking about buying one so we could ride together either at croom or if we buy into RR.

Anyway I was thinking about buying the Bombardier Rally ...

It seems like a good beginners ATV but is a bit on the weak side maybe, 176cc.  I'd like to not spend more than $3500 and don't want 4x4 ... it doesn't have to be new.  Any suggestions?  Also I was originally looking at the Bombardier DS250, but apparently RR frowns on these and my bro said that his is meant for mud not jumps/speed, so I think I should stick with something that I can tool around with him.  He also was telling me not to buy a chain driven ATV (and the rally is chain), cause it'll come off or get crap stuck all up inside it while mudding.

Any suggestions?  Where do I find a good selection of used ATVs?  I'm located near Tampa if that helps.

I tried several search terms but came up with sooo many results.  After about 30 minutes of looking for a thread like this I decided to one.
