You said it right: few years ago (or some more years!)
But today, the PC1000 is an old cam, no HD, the standard in the lights are LEDs etc.
So you can't compare the prices today with the good old times!
That's not against you. I see it very often in all this forums that everyone would sell his old stuff for a maximum of money! That's the good thing in ebay, there you find market prices!
Are LED's better than HID or just another gimmick to make the upgrade market blossom? I believe it is about 6 years old (ancient!!) I have been skiing for 30 years and in all those years and all the gimmicks they come up with to entice you to buy new, only 2 where worth the upgrade to new skis. but I digress. Do you have an offer? I think the econnomy has driven the secondary market down but prices on new are astronomical as always. Let me ask you this, why are you then looking at old U/W housing/cameras??
