Would this be a good RO/DI unit?

I was looking at some on ebay and found this one. Would this be ok? It's a lot cheaper than some of the others. Does anyone own one of these?

Also what is the difference between the one above and this one?

Thanks!

I have the second one and love it. The directions are kind of tough to figure out, but I do like the 4 G tank. You may want to check further down, those get posted and sold pretty quick. I got mine for $100, shipping included.

Glad to hear you like it. I can't seem to find one cheaper. the shipping is the killer. I don't really need the 4 gallon tank since I will be storing my water in a rubbermaid comtainer.

Can anyone tell me what the difference between these 2 systems are?

Sorry, I put the same link twice. I updated the previous post with 2 different links.

It looks like the one has 2 DI filters. They are both from the same seller so you can probably contact them for more specific info. I am interested in knowing myself....

I sent them a question. I'll let you know what they say. So do you think this would be an acceptable unit for my 90 gallon reef? This is one of the last things I need to order to get the tank up and running.

I was told that the one with 2 filters is used for reef and drinking water. The other is reef only.

The 1st link is just an RO/DI unit. The 2nd link is the same unit, but it has a 4 gal storage tank. It's basically the same thing I have. It has 2 outputs. One is the RO water that goes into the storage tank and then to a spigot on your sink. The other outlet is RO/DI for your tank.
