Power Conditioner Advice

I'm planning a major power overhaul to my system. This will include running dedicated 20amp lines and the purchase of new power conditioning gear. I currently have a Monster AVS2000 regenerator and PowerCenter....but I've decided to give some other equipment a try. I'd be interested in opinions about the
following:

1. Running Springs Audio
2. Equi=Tech
3. B-P-T
4. Richard Gray Power Company
5. Dezorel

Thanks,
Harry
