R/O Systems. I Need To Buy A Good One. Any Suggestions??

If it were me I would buy the $100 one it has more stages, and you could replace the membrane and still be cheaper then the other unit. RO units are very easy to install, tap a water feed, place your waste line and start filling your containers. The most important part of an RO unit is the membrane and most of the good units use the same high quality membrane, so it really doesnt matter which one you get just be sure it is a high quality membrane.

thank you very much for everyone who helped steer me in the right direction. i ended up getting this one: http://www.purewaterclub.com/catalog/product_info.php?products_id=323 i can not wait for it to arrive. i am also buying this today: http://cgi.ebay.com/ws/eBayISAPI.dl...98199&ssPageName=STRK:MEWAX:IT#ht_4100wt_1279 !! just need the C02 and another t5 and t8 fixtures and i will completely set up!!! i will be posting pics of my set up shortly in the Grow Room section, if anyone cares to peep. time to water! last time with store bought water!!!!!! so siked!!
