can someone reccomend an rodi unit?

[Maverick00]

Im throwing in the towel when it comes to buying water 5 gallons at a time. Can someone recommend a few that come to mind? I have been reading reviews and doing my research but still cant just put a finger on the one i should buy. There just seems to be too many to choose from. (buckeye, vertex, aquatic life, aquafx...) Ill be upgrading to a 60 gallon setup soon.
