i figure i will be taking the plunge in the next month or 2, but i am slightly worried of the chance of new versions coming out. i remember hearing rumors back in the day of new versions being released at some point and wanted to see if there was any new info out there. i know even if they do come out there will be minimal overall changes but i would feel bad that i didn't get the newest version cause i am that kind of person.

P.S. whats the rule on front mains separation distance?

Version 2 just came out recently, so I would not be to concerned about anything significant happening in the near future. You may want to call or PM someone from Axiom as we would have no idea.

Every room is different, but a good rule of thumb is to have them apart about the same distance as you are away from them, but this is not set in stone.
