New Engine Options

I have a 96 blazer with a 4.3l v6 vortec and I am curious what my options for a new motor are.

A reman from Jasper is one option,with a 3 year 100,000 mile warranty.I know ATK is one also,was about to about go out of buisness 2 years ago and a Chicago buisness man bought them out.Stay away from remans that parts stores sell,use the cheapest parts and the warranties suck.Plus you have to take it to one of their places for warranty work.
