Watch ebay for a fantom engine, they're on there every now and then. I just picked up a brand new 2005 FR12, in the box, for less than $80 cheers!. But if you don't feel like waiting, $140 is a great deal for one. I think fantom has been making inprovements to thier engine with every year. The 03's were great, the 04's a bit better, the 05's a little bit better. The 05's are suppose to have 1.4bhp and 37000+ rpm.
