I've almost gotten into several Eberron games, but they usually broke down and apart before I cleared my schedule and got in. And that's, honestly, left me a little wary about it. I've gone through the main setting book a few times, and all of it seemed a little too wacky and hokey for my personal tastes.
Warforged I just don't like. When I heard about them, I didn't like it. Somebody played one for a short time in an "Everything Goes" World's Largest Dungeon game I was in, and it was just silly. With a feat he was suddenly a walking adamantine weapon and was already immune to just about everything. Everybody at the table was playing rather power-gamey characters and a thrown-together-last-second Warforged made everybody else look silly. Beyond that, one of the games that died did so because characters were rapidly being replaced with Warforged because Warforged were so obviously superior to every other racial type and the GM got fed up. Heck, I'd have played one too.
Some people complain about Elminster in FR being Ed's pet cheesed out super-power ... at least that's just one NPC. Eberron has done this with an entire race, it seems.
After that, another game died because of the Artificer class. I had three different people come sob to me about how overpowered that one got to be, and again, with very little effort on the part of the player. Eventually, again, between Warforged and Artificers, a DM decided he didn't like trying to work with the setting anymore and killed the game.
I'd still chance to play in it ... maybe as a Warforged Artificer. But it would take a really good experience to turn me around for it.
