Matt is this the puller set you are talking about?
I got mine for 5 bucks on sale
and I have used and abused it to no end and that thing does a good job and is holding up well. I have replaced some of the grade 5 bolts with grade 8 but for all but the most severe jobs the grade 5 will work just fine. That little outfit is one HF's real bargains and is one tool from there I would recommend. They also have a dandy power steering pulley remover that is a fraction of the "real" tool cost but it too works really well and seems indestructible, I think I got that one too for about $5.
