I would buy smaller (700-800W) units and have one per machine. Any brand would probably suffice. I don't think there is a lot of difference until you get into the units that are very expensive. 95% of the outages are really just small brownouts that are enough to disrupt equipment. This is the main thing you need protection for. You only need higher wattages if you need to run for extended time (more than 5-10min). I have never had to go for more than a minute or two. I only have the machine and the PC on the UPS. I plug the monitor for the computer into the wall along with everything else that I don't care about.

A 1500 watt APC to cover 2 Amaya's and one computer is $699 (ouch!). Do I even need one? I have the surge protector I bought through Melco. I worry about the current in my shop being inconsistent.
