Yep, I did the same thing. I havent have the slightest problem with it yet. I was thinking about an upgrade to a higher HP model at the time, but I chosed the factory reman.
If I were to do it again, I probably would have chosen the higher HP from an aftermarket, or GM performance line, but I was not planning on offrading the Blazer then. It depends on your needs and wants.
But all around value, warranty, and avaiability, I would say yes.
