Do a search in the forums, and you will find nothing of horror stories. Their customer support is atrocious. Their core return policy is unbelievable, as is the amount they will ding you when whatever core you send them is not pristine. My own parts from them took over 6 weeks to get, and the complete kit which I ordered, did not have many of the parts I had been verbally assured it would have. Their paper work, and customer service is unbelievable, in a very bad way.
Search craigslist in Jax, Florida. I looked at one for $800 [whole engine running cond.] about 1 month ago. Customer bought something else, but a good deal considering manifolds, alternator, starter, etc... Had good dealings with Tad as well .
