Katech.
Not cheap, but really nice. And they make them in carbon fiber if you really want to get spendy...
I think I've already told you this, but I got mine from Scoggin Dickey and had them powder coated myself. Not sure if I saved any money this way, but Katech was out of stock at the time, so I didn't have a choice.
And I still may sell them once I finally get my engine back together and determine if the Holley's will work. Oh, and there are the Holley's also.

A lot cheaper, and look pretty good with the coils directly attached without the coil brackets.
