General recommendation for well water RODI unit?

[Stoichiometry]

Hi, I live out in the country in Montana and getting tired of driving 50 minutes to the LFS for water that closes by 6pm. I'm running well water here and don't know the exact parameters. Looking to have an RO unit installed just for drinking water soon so maybe the test from that company will help. But I'd rather not wait and order an RODI unit for my tank that should probably work. Anyone have any recommendations for an RODI unit I might need? Would like to order from BRS as I have some credit with them. Tank is small so I don't need it to produce a bunch per day. Maybe need a 6 stage?

With well water there is generally CO2 to contend with.
The water has to be degassed BEFORE being put through the RO.
Buckeye Hydro or Spectrapure are where I would look for help.
