The publishers indeed deserve accolades for their fine efforts. In no particular order, I'd like to thank...
Necromancer Games - For making some amazing cool adventures. My group has enjoyed such titles as Siege of Durgham's Folly, Hall of the Rainbow Mage, and Aberrations. I've bought several other of your adventures, and am chomping at the bit to run more of them! I also love Tome of Horrors 1 & 2.
Green Ronin - I fell in love with the Freeport series and based my 1st 3e campaign there. Even though I don't presently have any campaigns using Freeport at this time, I've continued to purchase the newer Freeport products, and I am planning to return there in a future campaign. BTW, I'm also totally pumped about Thieves World!
Malhovoc Press - Book of Eldritch Might 1 & 2 were some of my 1st d20 purchases, and those still see regular use in my monthly campaign. Great stuff, Monty! I also loved Demon God's Fane. I own Banewarrens, and would love to run that sometime as well.
Monkeygod Enterprises - I've picked up a few of their adventures, and I really liked what I saw. The Magic Dump was cool, and I'm hoping to work in Black Ice Well & Hellstone Deep when I get parties up to sufficient level.
AEG - I really must commend you for the Toolbox book. It is so wonderfully handy for its spur of the moment crunchiness.
Mongoose Publishing - I've purchased some of the Quintessential books, Slayer's Guides and Encyclopedia Arcane series. Though I haven't managed to work in all that much of the material, these books have provided lots of good ideas for me.
Pinwheel Games - I used the adventure Evil's Lesser Minions to get my current campaign started. I would love to see more from you.
WotC - Besides the obvious core books, I'd like to commend you for Manual of the Planes, Monsters of Faerun, Complete Warrior and Complete Divine. Those are books that I've gotten a lot of use from. Also, though I don't like the randomness or rarity system, I love the pre-painted plastic miniatures.
I'm missing a few other publishers, I'm sure, but those are the products that struck me as exceptionally noteworthy.
To all publishers - Please keep up the good work.
