Resale of items

My neighbor's kids are done showing now and i have offered to buy his cooler deal thingy majig and he said he would think of a price. its like a home or dairy cooler with a evaportor coils. what is a reasonable price to accept? also what is a good price for used fans? they arnt too old and only used for a few months of the year. thanks for the help

not going to be much help on the cooler.
What kind of fans are they? I just bought 2 24" Schaeffers off a a local family who just finished showing. They were in perfect working order but had the typical Schaeffer cage wear, not beat down, but dirty and some bent wires. Had $50 a piece in them...good enough to hang in the barn

they are turbos but i was thinking around 75

depending on condition 75 is resonable if they are in good shape i would consider up to 100

Cooler depends on size and cooling capacity on fans and such if in great shape I go half of new price and then adjust from there
