are there any companies out there that make 8 - 10 bulb 24 inch fixtures other than ATI?
Not any good companies. Sfiligoi might but it will cost more than an ATI.
Have you thought about running 2 - 4 bulb fixtures instead?
ATI came out with the 8 bulb Sunpowers and they should be in the states here pretty soon. They are cheaper than the Powermodules.
