how does something like this work? where do you hook it to the water system? also how much money does it cost to maintain? anything you need to replace so often or anything?
I have a faucet in my basement which I connect it to. Basically it comes with a faucet adapter which I hook up to, which runs a line to the RODI system. At the end of the RODI there is another line which I connect to a bucket which makes the clean RODI water. Also connected to the RODI unit to is a waste line, not all of the water is 100% cleaned so there is run-off. I connect this back to the drain or separate bucket. There is a pressure thing on the waste line which I allow to drip, and the clean water drips based on how much pressure I put into this line. It is easier to look at then to explain. Overall very easy. The only thing you need to maintain is the membranes, which are cheap for this unit. I believe they are suppose to last for 1500 gallons, I make about 10 gallons a week. I also use the water in my Keurig coffee maker and rice maker so this water is not just for the fish.

I would change the membranes once a year:

Also buy a TDS meter to see the before and after effects of water quality:

Also this is a good indication of when to change the membranes.
Once you buy the system and TDS meter, you only have to change the membrane once yearly or shorter or longer depending on the initial water quality. Overall its a one-time put over $100 down but yearly maintenance is cheapo. If you are ever in Boston let me know, you can always stop by and see how mine works. The direction sucks so its best to see one work beforehand. It takes time to make water, so its rated at 50 gallons per day. so you are going to get more of a drip then constant pour of water. All units are like this.
All these units have a lifetime warranty so anything is replaceable for free except the membranes.
Check out nano-reef.com also and search for mighty mite, people really love this unit and you can see pics of it, maybe someone has a pic of the whole setup also. Also they are a forum sponsor here and in many other places, a respectable company in my opinion.
