Love those map drawers. I have a few large-size drawers on a couple Gerstner boxes but I still find that plastic cases are best for some things like buck tails and a few other things. Easier for bulky items and sometimes it is nice to see what is in there without opening. So while I love wood drawers and would not hesitate to pick up a cool set of drawers like those (if the price was right), I doubt I would ever go all wood like I had imagined at one time.
Also check out that big flea market in Atlanta. I hear it is good. My desk is walnut piece I bought from a flea market in CLT. It looked horrible after 50 or so years in a auto repair shop but it cleaned up nicely.
