It is a crazy task these days to find a decent site name. Whatever a normal human being can think of of, it is already taken. Not only that, people used robots to lock in uncommon site names, created by combining words. Godaddy.com and whois.com etc., cannot really help much when you are researching a site name as you can enter only name at a time.
I use this site to find out what is already taken and what is available. Certainly saves quite a bit of time.
As you can see, siteterm.com .net etc., are available.
