i have been reading up on the all of the popular reactors that are on the market.
when i say reading i mean i have read the maufactures sites, googled it, did searches on here, read pages and pages of post etc... i mean i really did my homework, or a a thesis paper for that matter.
i have come to the conclusion that when i get the money together i will be getting a SCHURAN. IMO,i think it is the best on the market, and if for any rason i fall short of the SCHURAN i will get the GEO. by the way, if you decide to get the SCHURAN i would suggest reading up on it because from what i ahve learned about it, it uses a different type of media, and it operates much differently than the others (including GEO).....
i would stay far away from the others because of post that i have read about leaks, degeneration of the o-rings and acrylic, bad customer service, and trouble dailing it in....
hope this helps a bit
