[updated:LAST EDITED ON Dec-04-02 AT 03:19 PM (CDT)]You can get an active unit (http://www.cigaroasis.com/) which will regulate the RH and add when needed or you can use a 50/50 water-propylene glycol mix in your current device which keeps it at around 70%.
As far as a hyrgometer, though analogs look better (in my opinion) digital are much more accurate.
For Maduros, I love the CAO Maduros....other good ones to try out are Padron Anniv as well as regular Padrons (the A size Magnum Maduro). Ive also been smoking Sancho Panzas Maduros. They are a good cigar for the price. There are many more out there, but half the fun is finding them yourself (yes thats an excuse for my laziness...but Im sick)
