How much can I get for a Sun Tana Wolff System stand up bed made in July 1987?

I have a Wolff System Sun Tana stand up tanning bed and was wondering how much it is worth, or how much I could get if I was to sell it? I even thought about selling it for parts; what would be a good price for that also? Do you think a collector would want it?

Here is some information on the bed.

It is a white stand up bed, some of the wires may need to be replaced, and it has some dents in it, but runs great.

Hours on bed: 2571

36 bulbs

Model number: SW-36

Serial number: 252

AMP: 24

Manufactured: July 1987

Volts: 240

Thanks for your help!
