The new schwinns are on the cheap side but the older ones are great for most Mab applications. I don't have one myself but many do. As a bit of a warning, while the 2 stroke china kits seem cheap and while the quality of the kits are, you will end up spending much more then if you get a quality kit to begin with. Some don't mind the tinkering. I Don't, but bewared I have had to stop myself from working on my china girl because I now have spent almost 1000 dollars playing with the darn thing. I love it. Lots of power but not super reliable. I have heard the saying "Cheap, Reliable, Powerful, pick any two" And I pretty much believe it. (the HF motors might be an exception but I have not personally experimented with them)
