The only thing i didnt like about my blast was the very small limit of aftermarket parts available for it. I got an XB9S last spring, and never looked back. The feel from my blast to my XB9 was very weird, and i couldnt stand the feel of the XB9 at first. The 9 felt a LOT higher up, and very intimidating. I wasn't going to even buy it at first, but it sounded and looked so friggin' good, that i forced myself to adapt, and now i cant stand the way blasts feel.
If i were you looking for something fun and inexpensive, i'd go with a supermoto. Look for Suzuki DRZ400s and the such. Those are cheap and more fun than just about anything else on the road
