what do you guys think about used aluminum flywheels?

reason is because i ordered a flywheel from a reputable shop, but it been on backorder for about a month. they offered to sell me a used one (says its in good condition) for almost half the price... would you wait a few more weeks for the new one? $485 or go with the used one $300

 

used flywheels are fine. just make sure to check for cracks, or chipped teeth. also make sure the used fly already comes resurfaced.
