Well, I think almost all RO's are in adaquat for our water here as they always have a 1 micron as a first stage. To improve this I would put a 5 micron infront to catch the algae. that way you can change a $5.00, 5 micron filter say every 4 months and extend the life of your 1 micron filter.
you can reasonably expect a membrain to last 2 years if it is taken care of, and I don;t use a float valve on my top off storage where some do. I use that timer on the stove
I can't recomend any places as I am working on a deal to be able to supply RO's myself, but I can say to inquire about the GPD ratings and at what PSI they are rated. as I mentioned in another post a lot of companies are using membrains and giving the rating for the higher PSI. so what you will see id a 100 gpd unit for a good price but it will only put out 100 gpd @ 100 PSI. that same membrain is only rated for 45 GPD @ 50 PSI (which is more realistic for most resadential pressures.
The unit I just built for my self has membrains rated for 75 GPD @ 50 PSI and 160 GPD @ 100 PSI hence I have a comercial pump comming this week as I only have 40 PSI water pressure in my new house
