I think the market is depressed right now. The market doesn't lie. I've heard that some people do better on "ebay"??? Maybe so if your selling "generic.com"... but most names are "So-So.com", or names like "StoreBoughten.com". You have to question the bids some of those names get.
Keep everything in perspective. At least on DNF, you have recourse if someone tries to shill a domain. At least you actually know some of the buyers/sellers. At least you know you are "moving" on a name, that someone else "may" or "may never" buy. More times than not these names expire.
Oh...and again. The market is depressed. As soon as it picks up names like "StoreBoughten.com" won't sound to bad for $25. I think to add some spice to the auctions, why not add "other things" to attract people. Auction "services" by other members (i.e logos, website development, etc).
Just my .02...
