just think of it this way, if you get a cheapo one for 450, its gonna break something pretty quickly, and seeing you said you got no more money, its gonna be stuck in the shed broken!!!!
if i was you, id just wait and save till you can get something like a prox, Pitpro etc, you only need like 200 more, and the difference in bikes will be heaps better,
rememeber these bikes need plenty of maintenace and repairs, its not just a case of spending $450 and riding it for a year, things will need fixing...
Yeah, thats my point exactly.
