There's a myth that all the good domain names are taken. You hear it a lot on forums such as this. But it really IS a myth. All the good domains are NOT taken - all the obvious ones are. And that's not the same thing at all.
You're clearly at least some way concerned about your domain name issue. I'll reiterate what I said before: You need to own the .com. Stand in front of a white board for an hour, and you'll come up with something you like that's both available and readable.
I'm reminded of a story from about a year ago: a website devoted to red headed people, and how they were in danger of extinction. Apparently redhead.com was unavailable, so they chose to spell it differently (don't ask me how you could spell those 2 words differently, but they did.) Anyway, it turns out that redhead.com lead to a porn site, and to this day that's the only thing I remember about the endangered red heads website.
Another story that springs to mind concerns a local business man who loved his domain name so much, he didn't care that it was almost identical to a major competitors. Without naming names, we're talking something along the lines of carsdirect.com Vs cars-direct.com. The first URL was already established, the second was the one he wanted, so he carried on regardless. The domains were so close that he even printed his business cards with the wrong domain by mistake, and never even noticed. I'm not messing about here, this really happened to a guy I know.
Business first. Personal preference and taste, second. You are not your customers.
Also I noticed they have .uk.com now how many do you have to buy :|
You've got to buy the big three: .com, .org, and .net. And it helps to own your local one too: .co.uk, .de, .fr, whatever. If you don't own the big ones, then any single dissatisfied customer can acquire it and seriously damage you. Example: frets.com - title: "frets.co.uk sucks!", and they'll be on the front page of Google right next to you when your customers come calling.
