Well, I could see myself with one of those! Actually, I'm surprised I don't have one of 'em yet!
Honestly, if you're just doing automotive stuff that requires 13.8VDC, look at Astron power supplies, they're found in every ham radio store. They can supply from just a few amps to well over 75A, and can be had with no meters or voltmeters and ammmeters.
Personally, I use an Alinco power supply like this one:
It is extremely light (unlike my 40+lb Tripp-Lite from the 80's!), supplies 32A of power, has a cig outlet right on the front, as well as 2 spring-loaded connector sets on the front, and two screw terminals in the rear of the unit. It also has a volt and ammeter, and you can adjust voltage up or down, as well as tune the unit for noise (switching power supplies can be "noisy" to radio equipment).
If you require more than 30A, I would suggest an AGM battery with a charger attached to it instead of a power supply. Its cheaper and will supply way more than you'll get from a plug-in power supply!
