It's a wave. This happens a lot around here. Part of it is that Don will build YOUR cabinet but if YOU have no idea how to design it, well you can figure out the rest.
I've had my share of Don's work. He makes a great cabinet. His tolex work is stunning.
It boils down to cost. You can buy a off the shelf box or have something custom done for the same or less!
Yep, nail on the proverbial head. The key is to know what you want (& have a pretty good idea it's a proven design) from the get go.
