best price?

I don't think price is the only thing you should look at here. To me, the G-force extended hubs are the best way to widen the rear without going for an aftermarket axle, and they don't cost much more than a regular spacer. I never liked the idea of spacers to begin with, because all it does is add weight and adds more stuff to break, loosen, or generally cause problems.
 
the crj wheel spacers were kind of expensive but they are very strong. I weigh 285 and i rode that thing hard a few times and came down hard a couple of times.
 
yeah i checked em its saying no extended hubs for blaster but the ones i found were only "1 1/4" per side so i dont kno just yet ima keep looking not in any hurry to buy lol
and thanks
