eai just plain sucks. they screw over their dealers, they publish and distribute a catalog once a year, and only give it out to a select few dealers, they change their prices at a moment's notice, and they're rude little bastards.
they have a lot of cool NOS stuff, and their cogs are pretty nice, but from a dealer/shop standpoint, they're just not worth dealing with, unless you're "down" with them.
