I own both a Caster F8T truggy, and a Jammin (buggy, but similar overall design to truggy). They are both very solid vehicles, either one is a good choice IMO. The Jammin will have better parts support at LHS, and lots of "chop shops" on Ebay selling X2 CRT parts for cheap. For me I don't have any LHS around me so I have to order everything online anyway.
