im looking for some input, a couple of my buddys each have a quad for sale, a 2001 400ex for $2,400, or a 2002 660r raptor for $2,300. both are mint but the raptor needs new rear bearings, what one do i go with. i love the reliabilty of the ex but, i hate to pass up the power of the 660. let me know what you think. thanks
