Best resonance machine to buy

I recently came in contact with someone who owns an Srt. Square Resonance Machine and had subtle but good results. Are you familiar with it? I'm told the cost is $4000 plus training. That seems steep compared to this conversation. I'm in the market for buying a machine and having trouble finding in-depth research and figuring out what would be the best one for us that will include support. I'm a licensed massage therapist for the past 15 years, a life coach, and wanting to incorporate this into my business. Thank you in advance for your help. Tweet
