If you're going to dedicate one guitar to DADGAD you might want to use a slightly heavier gauge in the lowered strings to avoid flabbiness and fret rattle. D'addario makes an affordable set, EJ24, designed for DADGAD and I think some other makers do as well. Fortuately, I also like this set for Drop-D Irish/Scottish backup on the 0000-sized guitar I use them on.

I think DADGAD was a wonderful invention and I still play a bunch of fingerstyle tunes with and use it for a few songs as well. It might not be for you but it would probably be fun to find out. Plus, you can also slip into Open-D from there quite easily.
