Who has an RO system that they like and recommend?

I live in an area that uses chloramine, has a ph between 8.4 and 10, and an EC of 0.50.

I'd like to get an RO filter that has a carbon pre-filter because apparently the chloramine will eat the membrane of the RO filter otherwise.

I'd also like one that has economical filter replacement. How standard are filters?

It'd be nice to have the clear canisters to be able to see how dirty they are.

I don't need a bladder tank because I'll probably run it to a float valve and then shut it off if I'm not around.

Anyone have good recommendations of what has worked for them?
