I need to buy a Reman 22RE for a customer of mine. Anyone had good luck with any places? I haven't bought one of these in a few years so wanted to get peoples opinions. Being that I have to stand behind this engine I want to make sure im not buying junk that will start knocking in 10K miles. There are several builders on Craigslist, but some prices seem to good to be true. Any info would be great. Thanks!
