I switched to be in the new chassis, also got a good deal on the BB. Having been boosted for the last 3+ seasons there where times when I couldn't imagine having boost either, but none of my riding group is boosted, and honestly it's more fun when everyone is on roughly the same playing field. I have really enjoyed being back NA and don't see a need to go back, these new sleds are just amazing in their abilities with a few small tweaks to fit each of us.
It does suck when sleds are driven down with the low price of others, but frankly I've ridden with many people with turbo's and their abilities don't match the sled they are riding. I still haven't been able to out ride my sled I've got now, let alone with it being boosted. I'm also with Kaleb, boost is just really expensive and it is next to impossible to take along to the next sled, especially with chassis and motor changes we are seeing on a consistent basis. I parted my sled out and made MUCH more then the highest offer I got on it, might be a way to go for some of you who's sleds are as modded as mine was. Stupid thing is worth more in parts then as a whole.
Maybe someday I'll be back, but it'll be on someone else's dime, taking the upfront hit, before i'll take the 4-5k hit myself. Just my .02...
