I was lucky in that my girl gave me a $200 gift certificate to www.petsolutions.com
for Valentines and I want to put it towards a good RO
unit. Any suggestions on which one to get? Here is a link to the ones that petsolutions offers. RO/DI's
please advise me which ones people have used if any along with the likes and dislikes if you own any of them! Thank you!
