Oh great thread! I'm upgrading from my hh and so far it's between the mini cc and a bethleham piranha. I know I'm going to want to do boro soon so that may leave the mini cc out and I see those of you who have it are already thinking of upgrading so that may just be what I needed to see to scratch that one off of the list..
I think for a while I'm going to be using tanked oxy(...little nervous about that...) until I can afford the concentrator. Looks like the majority of you like your minors. Can anyone tell me how they differ from the bethleham piranha?
