You're gonna love http://www.ammodors.com/ They sound like they'll be right up your alley.

It also sounds like you're not the kinda' guy who is going to tinker with and check on his humidor on a fairly regular basis. Therefore, I would HIGHLY recommend going the Boveda packs route vs. any hydration system that requires a fairly long learning curve and attention to detail. Boveda is as close to "set it and forget it" that there is on the market. Yes, you can skin the cat other ways - but I think your 'other ways' results may be closer to what you're already experiencing. Tupperware, Boveda and cigars: simple. And your Boveda packs can come in contact with your cigars; other systems - that's a big no-no.
