I recently launched - http://www.namemesh.com and would love to have your feedback on it.

Briefly:

NameMesh is a smart .com domain search engine which quickly creates, ranks and checks names.

It's

1) Complete - checks for lots of things like synonyms, antonyms, related words, portmanteau, misspellings, phonetic variations, short url, acronyms, suffixes, prefixes etc.

2) Relevant - ranks all the names based on quality metrics. supports ways to do complex queries.

3) Simple & Fast - single step process taking only seconds.

Thanks
