another should i??
904s are great...I would say it's a gamble however. You might do just fine and it be a good deal from someone just wanting it gone or it could be toast?? Just because it was rebuilt dosn't mean it up to snuff now. If I were to get it for 50.00, I know I would have it overhauled again to be sure before she's installed.
Sometimes trying to save big...ends up costing more in the end!!
Just my 2 cents.
