Yeah, there have been good pieces of advice from both sides of the fence. The comments have come from good guys who know their chit about motors.
If you have the time and resources to do so, I would say go ahead and buy it. You could go and buy all of the parts and have the block sent off for machining--if needed. If not, go ahead and buy a brand new rotating assembly. You can build it slightly stronger than stock--if you want, depending on if you decide to keep it N/A or FI. You could salvage most of the upper end of the motor, but you will need to replace the whole bottom end rotating assembly. I would make sure to get new gaskets and such as well.
