Does anyone know of a good resource for comparison info on dehumidifiers? - I am spending some time in Florida and would like to keep a few things at a more regulated and lower humidity. There seems to be a big price difference between units I have seen. The obvious stuff like volume of water processed I under stand but would like to get some more insight into feature/cost comparisons. Since I have no reference point coming from a very dry desert area, I would like to get more educated on the subject before I purchase. Any advice or warnings are appreciated.
