Just take it to any decent machine shop and have the crank machined. They could do just the rod journals 0.10 over and leave the mains STD (they would micropolish it). It would cost $100-120. A set of quality fitted rod/main bearings would cost about $60. Minneapolis Crankshaft Supply in downtown Mpls charges under $180 for the whole kit (return your core) and ships worldwide, but really any machine shop anywhere could do it without messing up. Machine shop 101.
Make sure you have them check the rods as that one rod will likely be out of round. My machine shop charges $10 a rod to resize the big end, but that's pretty cheap.
Boiling, checking, and mic'ing the block runs about $100 and honing adds another $10 a hole.
The rings should run about $60 for the updated Hastings set; more for Toyota. Or do pistons and rings together for about $110 (cheap Chinese available for $70), but then you really should bore 0.10 over for another ~$100.
SO.... my point....DON'T buy a used motor. Have your current motor refreshed. It should be rebuildable.
