Tools & Fabrication - Help Pulley puller choices?

I did the search and everyone seems to like the sears or autozone one. I think I'm missing something here. The 6in puller from sears is 139.00 and the oem one from autozone is 16.00. Why the difference? Are there others that would be OK. Since I don't feel like spending 140 bucks for the puller. 50 or so is fine. Any help would be appreciated. What puller is used on the ls1howto.com in the head and cam swap area? That one looked good.

$140.00 :cry:

i like to use the ones with a finer thread otherwise you'll get distortion at least thats what ive found other than that they are all pretty much the same IMO

i got 3 sizes at harbor freight for like $9

Borrow it from autozone on their loaned program. Get all you money back afterwards. Best part is even if you break it your fine since all the stuff has a lifetime warrantee
