I started out by having a plexiglass case made that would hold two stacks of five cedar trays with enough room in the middle for an Oasis. Worked well, just didn't have temp control, which is a must down here in south Florida. Custom case cost about $100.
That maple humidor is gorgeous! I'd love a custom wood humi like that at some point. I'd actually prefer that to a glass-front I think. But I'd need it much larger and probably multiple doors (which should help with humidity control).
I found out about this guy, Dave Arnold, on cigarpass I think. I am not a member there but was peeking around one day in the for sale section and found his ashtrays. I figure since he's so close I'll have to check him out sometime.
