I would like to know the approx. value of my equip

Yes, Use Audiogon bluebook. THEN, to be safe, subtract 25 %!
It seems to be a buyers market out there. I've rarely gotten the bluebook when selling unless it's a high demand item. If a company is out of business, it can dramatically affect the value in spite of what the blue book says. I own Snell Type A V5's. They won't fetch half of what Audiogon says they're worth. This is as fickle a hobby as any. If you accept this principle, you'll sleep easier. Joe

Jnovak, Now that's funny.

When selling, I've beaten the BlueBook a few times, and I've had to go way below the BlueBook at times. It just depends on the item. When buying, I've paid above BlueBook if I just had to have the item and it was one of the very few around.

I agree Jnovak, Audiogon Bluebook is wishful thinking for a seller. :)

Bluebook may be high or low. You really have to look at the data, assuming there is some detail, and be honest with yourself about what you are selling, instead of thinking that you will get the highest price posted for a sale.
