Greetings seasoned reefers, I just signed myself up for reef adventures by
purchasing 55G tank and have been reading megabytes of info on
reefcentral.com. I suppose my first purchase (after the tank) in this
endless adventure will be RO/DI unit. Yes, I know that I'll be using it
alot, and should get the best there is, but I am, like most of us, is short
on money... So, the question is what you gurus would recommend to get and
where, so it will accommodate 55gallon tank needs, but wont force me into
bankruptcy?

I do not understand how one could be forced into bankruptcy paying
about $100 for a complete 6-stage filter (including deionizer "DI" stage).

Check for that example eBay.com, Item# 4398719599 and others.
You could spend a little more and get the system with the pressurized
tank for drinking water storage under the kitchen sink...
This way you would have pure water for your reef and your drinking.
