When I see it unregistered I almost think someones going to snatch it up in minutes so I usually click and buy, thinking later if it was good or not.
After that comes a few minutes of buyers remorse (yeah on $8) and then the domain goes in the pile... to be developed.
A domain I bought last year has recently had a surge in type in traffic and is doing rather well ad wise. It sounded like a silly name at the time but now it's becoming a common search term. Gotta love that.
The moral here is there are still great domains out there to be had, if that's your gig.
