Good perspective ... It's going to have to be a big, broad market with almost half a million LLLL.com out there to choose from (well maybe more like somewhere between 100,000 and 300,000 still held by resellers - we'll have a better picture of that number "real soon now" but safe to say it's a bit more than a few tens of thousands as with LLL and even CCC.com ...)
You don't always have to be dealing at the high end to make decent money though IMO (but that's certainly a nice place to be if you've got the capital and know what you're doing) ... I started digging through the "druss" back in September simply because I wanted to get a semi-decent one for my own use while I still could. I found quite a few that I liked, so I regged them "just in case" - couldn't really make up my mind which one I really wanted to use or might want to work with later ... And then the buyout frenzy hit - a pleasant surprise, especially once I found I could still get more even nicer ones in the aftermarket still for less than than the $35 I would have paid for regging at Network Solutions 10 years ago ...!
I'm not expecting to sell many for more than $100 anytime soon, if ever. But think about the size of the "very very small business" or "personal enthusiast" market ... If Peter can't get PJFI or PJFT for an affordable price - well, PJFX or PJFZ might still be a "cool" short, memorable URL to work with - the "Peter J Foti Zone" or whatever.
Ten years from now, people are going to look at any short URL with the same "must have been around for a while and knew what they were doing on the net back when 2, 3, and 4 letter domains were still available for less than $100,000" reaction that we have when we see 2 and 3 letter .com addresses today. IMO.
