I trashed my mfos wally Evil or Very Mad

I ordered a frequency central l kit to try it out. $30 shipped to the us ain't bad.

I'll be needing More 12v bipolar power in the near future, anything prebuild that is cheap or kits? Curious what everyone uses.

although it says dual supply that is NOT a bipolar supply. It just has 2 voltages: 5V and 12V, and the 5V has the highest current output.

This is the droid I'm looking for!

The one you linked seems to be a single supply but you might be able to use 2 of those. I do wonder how bad the ripple is with that current rating
and if it is very stable at low currents.

Note that although the labels say V- that is just your GND connection. Also the photos aren't aways correct, I think the previous one you linked
actually had the wrong photo as I didn't see the 5V output.

third time's a charm ?

edit: the RT-65B seems to be closer to what you're looking for, but for that price you'd be better of with 2 seperate 12V supplies and have more current.

I built the Metatronic Mods power supply, very nice. They sell only the PCB but the BOM is easy to fill (I did it with one order.)
