Longdo - Amazing resource. Ability to search across many languages (English - Thai, Japanese - Thai, German - Thai, French - Thai Dictionary) With English-Thai it searches across multiple databases, returning good quality definitions. It will also return Thai definitions for all words on a webpage by entering URL.

Sascha - Only 630 words in this dictionary's database, but it does have the extra ability to translate German-Thai / Thai-German.

Thai2English - Was an excellent easy-to-use dictionary, slightly less comprehensive than Thai-language.com but the Thai section was recently made unavailable :(

Another good dictionary that I have only just discovered is SEAlang Library's Thai Dictionary. It seems to be new but looks to be very good, many options for searching, it is much more complex than any of the others I seen. Good for those that already have a good knowledge of both English and Thai.
