For stating trials, I hear the Zebdi is the choice.
Its okay. I bought mine because I didn't know anything and a LBS had it built up for sale. 800 total. I figured that was cheap if I didn't like the sport.
Its good for learning, but I think there are other/better frames out there. Its relatively bomb proof, and you bang the hell out of it (you will when you start). Otherwise, you (like me) start building up a great component set and all you have to do later is change frames.
I'd go with a longer bike as well. IMHO. Andrew is correct, after riding various things, I like the Koxx.
