It is, actually. The only change I'm making is replacing the pots with Bourns precision 10-turn wire-wound pots (P/N 652-3540S-1-202) from Mouser. They were $13/each which adds almost 50% to the cost of the supply, but it should allow for much finer control over the voltage. Oh, I also had to get some .25" set screw type knobs for it too, because the original pots have grooved shafts.
Oh, and I'm going to heatshrink the leads on the ICs. Check the photos for why.

I mean do you find the variable AC ( Output AC: 1) 6.3VAC @ 1Amp, 2) 12.6VAC @ 1Amp Input: 110VAC ) useful?

I think it would probably be worth it, but to be honest, your DMM is probably going to be more accurate than those panel meters.
Personally, I'd still go with the kit, and get a pair of stackable banana plug leads and just run your DMM in parallel with the PS. Then you get the greater (albeit non-adjustable) amperage, AC out (if you need it), and the fun of building it. But that's just me. :)
