I am looking for a website, which is possibly in a lot of people's favorites here.

I can't remember the name, but it had a search engine to look up domain names, thesaurus names, combos, etc. It also had ways of looking up LLLL, LLLLL, and LLLLLL names by being able to alternate which letter is where.

I think it had a vertical menu on the left side, dark red maybe? It also showed if the domains were taken, available, or on auction.

Any help would be great.
