I'm in the process of building out my portable kegerator and came across this website that sells brand new kegs and saw their "belmished" section:
https://bvrgelements.com/product/Ball-Lock-New-3-Gallon-Blemished/
Brand new 3 gallon ball lock kegs with either some discoloration or dents for $49 a piece. No one is going to be looking at the kegs inside of an ice filled cooler and for $49 for new ball locks, it sure beats buying the used $29 pin lock kegs with loose handles, plus ball lock conversions and new lid, you would easily be at $50 going that route.
