I would suggest getting an ultrasonic fountain fogger. They're a little more expensive up front but replacement disks are readily available. The one I'm thinking of has a little buoy/float thing you can buy for it what keeps the fogger at just the right depth under the water no matter how big a container you put it in. You'll also need a fan to blow the fog around, since the fogger itself doesn't push it very far. But for under $80 you can make a nice, powerful humidifier with totally replaceable parts.

Hmm...I haven't seen a model like thew one you describe....the only ones I see are like the exoterra type....no floating ones....

Interesting!..and a small fan will blow the fog around the chamber?
I bought a fogger shown by seedjar, and was inspired by the following YouTube video to make a contraption which I affectionately call my "Fog Box."
I used a Tupperware container, some tubes, duct tape and hot-glue to seal it. It fills up my 29 gallon terrarium in a matter of minutes, and thats with only a 3" under-powered fan. Perhaps if you took that idea and upped the power on the uptake fan, you will find it meets your requirements.

Have you tried soaking the disc with white vinegar to remove any mineral deposits? (Or if the disc isn't removeable, just put vinegar in instead of water and let it stand.) I clean my cheapo Target off-brand humidifier after every few months of use.

I would suggest to ditch those small ones as well. Go for the big one and then use tubing to route it inside the tank...this is what I do myself.
