Cannondaleriders

I have been looking at alot of quads such as the kfx, predator, and cannondales and was wondering with the cannondales how much maintenance is required and how reliable are they, i want to know what im getting myself into. I see there very cheap now compared to the predator and kfx almost the same price if not less. Im not very good mechanically and i dont like doing alot of maintenance on it i rather be riding it then fixing it. If anyone can help with my decision i would appreciate it

Thanks
