Whoa! Why didn't I post this question sooner! Thanks a lot guys, this is very helpful.
I'll call these Rocket guys and see what they have to say and will compare it to the shop nearest to me (about 1hr away). My thinking is that the cost will be relatively the same, it's a matter of paying shipping versus paying Mass sales tax. The near-ish by store has one other advantage in that if I have any problems, I can drive down the Pike and have them take care of it as rather than shipping it elsewhere. But we'll see what either dealer has to say.
