There you go, you're ahead of the game already. There are few nasties in our water here as well, all within allowable limits for drinking, but I'm still glad I now have a RODI system and have been using the RO for drinking water, coffee, making beer/wine and occasionally when I'm cooking, like making a fine gravy or something.

Since you've confirmed that your water is chloramine treated, you will need two carbon stages before the RO membrane in order to protect it. Should only need one DI stage though, same housing as the pre filters. The one linked to on eBay with the 3 DI stages stacked horizontally is not only overkill, but very inefficient due to the horizontal mounting configuration. I'll reiterate that a TDS meter & pressure gauge are two items no system should be without. You might even want to pick up a handheld TDS meter & check your tap water before buying the RO system. I found one at the local WalM for just under $10. Should be in the aisles close to automotive stuff, where the RV gear is. They sell them so people can check the water they hook up to with RVs when traveling.
