David. I would have thought that ANY selling to a photo business would be somewhat disappointing. Pennies-on-the-dollar is how they work. The benefit is convenience. If that is more important than getting top dollar then it is a good deal.
Best place for immediate cash: a descriptive ad with a good price here or on almost any photo forum.
Next best place: eBay with the same caveat. The cost of doing business is a bit higher with this method due to fees.
Pro: you'll sell. Con: you could get conned. (Unlikely, but it happens - both on ebay and at photo forums.)
