Protek vs. Xantrex Power Supplies

Hi:

I'm looking for a triple output power supply. I've narrowed down to two Protek models, and two Xantrex.

Requirements:

1. Dual =>30V outputs and one 5V output
2. =>2A on the dual outputs
3. Voltage fine adjust pot or 10-turn pot on dual outs
4. Separate digital meters for volts and amps on both main outputs
5. Series and parallel capable isolated main outputs.

Preferences:

1. =>3A main outputs
