A couple of people on here use those reptifogger things. They look solid, and the flexible hose is pretty convenient, but considering what they are they're a little overpriced, IMHO.
I went ahead and bought myself a Sunpentown SU-2000 after much flip-flopping. In the end, the simple fact that it's more cost effective than purchasing two or three disc foggers won out. It cost like $60 whereas the least I could have expected to pay for a bucket fogger setup was about $70 (at least two discs, a fan, a bucket, and some PVC pipe). I expect the result to be... well, not a whole lot different.
I'll let you know how things look once I get everything rigged up and fogging away.
I also threw in a Hygrotherm on that order so I can control the humidifier more precisely. New toys!!
