Neat poll, Crothian. There have been some unexpected responses so far, so I'll chime in as well:
Avalanche - I don't need anything that they've offered thus far, although it generally looks to be pretty well done. The cheesecake factor doesn't bother me.
Bastion - I can't stand what I've seen of Bastion's stuff -- the art is terrible, rules elements are poorly done, and even when the concepts are good (Airships, Arms & Armor) the execution leaves a lot to be desired. (I got A&A for free with my Dungeon subscription, but I don't think that counts.

)
EN Publishing - Like Avalanche, I haven't been interested in what's been offered thus far.
Fast Forward Entertainment - I thought their first releases were of very poor quality, and as far as I can tell nothing has changed since then.
Fiery Dragon - Haven't needed anything they've offered.
Mongoose - Overpowered and problematic rules elements coupled with bland layout and a generally low-rent feel have always turned me off to Mongoose's stuff. I avoid collections of OGL material (AEG's Feats, Mongoose's own Ultimate books, etc.) that contain Mongoose material because I don't want to worry about fixing it. Probably my least favorite d20 company overall.
Mystic Eye Games - Never really piqued my interest.
Pinnacle - I've only seen their Deadlands stuff, which isn't really my cup of tea.
RPG Objects - Don't know the first thing about them.
All IMO, of course.
