I think the problem is that people don't have a lot of cash laying around, I know that's the case for me ! I think people understand that it may cost more to piece something together but it's easier to come up with 500- 600 bucks at a time than it is to say go with a complete motor for 6,500 or more ! That's what a lot of my buddies are doing ! Plus I think people are scared of spending 6,500 and up only to find out they there are big problems with what they have ! Now they may be out another 2 or 3 grand ! Just my good luck in how every you decide to go !
