So I bought this ring flash on eBay not too long ago for a little over sixty bucks. It's an old SunPak from the 70's or 80's. Fair enough. Here was the description:
Originally posted by seller: Sunpak DX 8R Ring light Flash unit for Macro and Portrait photography. Auto and Manual mode. No TTL, has only one electrical contact. Will work with most film and digital cameras. Has a 52mm thread for attching onto the front of a lens. Also comes with a 49mm step down adapter. Will easilymount to most Pentax lenses and Nikon lenses. Other lens sizes can also be used with a step up or down adapter that matches your filter thread size, easily found here on eBay for a few $$. Ring lights are used for a shadowless effect.
Condition:
USED - Tested, works great, see pictures.
So I got it in the mail today and I was pretty excited and went and bought batteries for it on my way to work. I couldn't seem to get the flash to pop though, and I took out the batteries and saw some pretty bad corrosion damage on the electrical contacts. After a little bit of jostling the, I seemed to have made contact and it's popping now. Still, I think that battery corrosion is a pretty serious defect, and should have been in the description. Especially since it seemed to be affecting the performance of the flash.
So I emailed the guy, and he asked if I wanted a partial refund. I told him that if the corrosion had been in the description, I wouldn't have even looked at the listing twice and that he'd have to go down pretty far for that to be acceptable and I'd rather just get my money back.
So I ask you, what do you think would be a fair price for a flash with corrosion damage?
