I am also on Rattlesnake, and put in a comprehensive filter system that works great for filtering lake water. First is a sediment filter, then a UV, then a R/O for the fridge & a drinking spigot at the sink. This is the best tasting water I have ever had, and everyone that tries it also thinks so.
We bought it from WaterTiger (
www.watertiger.net) in Canada, and the customer service was really great. I think we spoke with Eric, and he spent a lot of time walking through our requirements and what we should be looking for. We got the Silver Water combo system, and the plumber we used had no problem installing it.
You can PM me with questions - in the spring you can come by and see it if you want.
