High Current 12V power supplies - $75
Thought I'd share this link:
These units are still in production. The current new price is $1090 ! These will run on 120 or 240 VAC since they're switchers - the current is limited to 125A at 120V input. I checked the data sheet and they weigh less than 5 pounds...
