You can google or ebay for "bench power supply" but they start to get 
expensive if they put out any decent current.

How about a computer power supply?  Newer ones have high current on 12V. 
  They usually need some load on them to start, and you need a switch on 
the motherboard connector.  I rigged one up at work, can check tomorrow.

Personally, I just use an old battery for that stuff.  You can buy a 
lawn tractor battery for <$30 that's nice & compact, for portability & 
storage.
