I recently bought one from http://www.airwaterice.com/category/1/
Haven't installed it yet, so I can't really vouch for it. However, they answered a lot of my questions and offer lifetime warranty on parts.
I opted for an additional membrane which according to them would make the unit much more efficient roughly 2:1.
so I decided on spectra since my lfs had it in stock. Just a few questions how long is the breaking period? It seems I made a gallon super fast in about 10-15 minutes. I also heard you shouldn't use the first 5g of RO/DI.
Also is it normal for my faucet to leak due to pressure?
The pressure from the system is 60-61psi
