Shelf life of EAZ-Lift?

Greetings TM Gurus,
I've found an EAZ-Lift WD hitch for sale (750 lb tongue weight). They guy used it for one season and then it's been in his garage for a "few" years. The pictures look OK and there doesn't appear to be any rust - just some dust. The hitch will cost me about $200 including the gas needed to drive the 400 mile r/t to pick it up. The hitch includes the adjustable shank and the 2" ball.

1) Am I looking at trouble buying a hitch that has been sitting in a garage for a few years?
2) I could spend $130 more and buy a new EAZ-lift from PPL or smilar place

Any advice?

Thanks much!

Ted
