The bigger issue will be that there's no "do this, then do this, and then this" instruction manual. You have to work from the schematics, parts list and description he posted. The soldering of the DAC chips may be a little tricky for somebody who hasn't done much with the soldering iron in a while, but it really isn't a tough project.
As long as you put a fuse in the wire to the battery (its cheaper than other parts that will go up in smoke if you make a mistake), you should be able to put the kits together pretty easily. They are much easier to build than the original DDDAC which hat no text screened on the PCB.
The kit doesn't include a battery checker anymore (but its easy to build from scratch), plus you need to get switches and line out and power connectors, coupling caps and other parts on your own. Don't underestimate the cost of these items.
