Fair market price on "Fat 5" wheels

[HPsauce]

Hi, not sure if this is the right place to post or not, so feel free to move or delete.

Basically I'm interested to know what the fair price is for a set of 4 8.5J * 18 "Fat Five" wheels as there's a set on eBay that I'm "pondering". Obviously condition is a factor and these are not perfect, but I won't go into details on that - though general comments would be welcome on how condition affects value.

If the seller is a regular here, apologies, but the location doesn't match to anyone who has "declared" themselves.
