If you can find the Radio Shack one, I highly reccomend it....
I can't find the one I'd really like to find - it was sold on Ebay under name Samlex. I beileve they were at one time making the supplies for Radio Shack. I don't think my current Radio Shack is a Samlex. I knew several who used 25a Samlexs for bench supplies (they were not a switching type supply) and they lasted for years even under abusive conditions - pulling 23 - 25a continuous out of a 25a supply.
Thats a prob with the switching supplies I've seen, they don't seem to last long if you're using them at the high end of their capacity. I've pushed mine a time or two - two 0610iNet Hyperions charging at 10amps each and the smell it left in the room was a warning. Reason I added the other supply.
