which ro unit to get?

[smokinreefer]

just though ti'd pop in, just so you guys know that i am following my own thread [img]images/smiles/icon_biggrin.gif[/img]

FWIW i am using the TWP right now and have been for years. but i am currently using about 2 gallons a day for top off and the TWP is a bit of a hassle to use.

so i just want to look at my options.

but yeah, has anyone here recharged their cartridges? i sure would like to know how.
thanks
