Here is my advice:
Buy a non supercharged model.
Fewer things to go wrong and less expensive to fix when they do. I had a 2004 SC that gave me no problems during the 6 years and 100 hours I put on it, but the 2003 model I had prior, had an early engine problem (loose camshaft bolts from the factory) and my current 2010 RXT X has a shaft failure ($1,500.00) and will need a scheduled supercharger rebuild at 100 hours ($1,500.00). The SC Sea Doos are allot of fun, but they cost an arm and a leg to fix when they break and they do break.
