I would be very hesitant to using anything but Spanish cedar. Some of the reasons would be.

1- smell... other woods are going to impart their unique smell into your cigars especially if you have any in longer term storage. Honduran mohagany is probably the only other wood I would let my cigars permeate with as it has little to no smell. The wonderful smell of the SC is one I am ok with infusing into my cigars. American red cedar can be used but it has a much stronger odor and many believe it can overpower the cigars.

2- humidity... Most other woods will increase the issues with humidity control. They don't do as good of a job at helping regulate humidity.

3- tobacco worms... It is claimed that the smell of the cedar helps keep the tobacco worms at bay. I don't know if I buy into this because every cigar beetle problem I have seen have been with cigars in cedar humidors. Is it possible the problem could be worse if other wood was used. Well maybe.

Finally. I would guess that the average wineador can have from $2000 to $5000 and up in cigars in it. I wouldn't let saving $200 put my stash in any amount of risk.

Just my two cents on the subject.
