I wouldn't recommend it. I guess you could say they are a cheaper kit (what, like 240 or something) but then add carbon reeds, HC head, etc.
My friend has one and its decent, I think it probably does like 45 with an estoril, but tuning it is tricky, and in riding it, there just isn't much power, not like a polini.
So yea, I'd get a polini. Sure they break, but all kits have the potential to do so, and cost is close, maybe a little higher for a polini w/ 4 petal reed block. The power difference is night and day. Either that or go gilardoni because that is the best deal for a kit/HC head.
