I would have to go with the glass...
in fact, I did. My home humi does have a glass lid. Though, I do plan to get an all wood one for my desk at the office.
i have a glass top and wood door
Having that glass top has sparked a lot of conversations w/ guests at my house. I have
never had a problem w/ my smokes drying out or discoloring, but it is not in direct sunlight.
Get whatever you like best--you are going to be the one looking at it . Either way you go its going to look better than the old coolidor.
