Thank you very much Todd!
Before signing up for Praxis, I learned that they don't have Midmark ECG interface. That will require purchase of software from Midmark. In addition, I just paid AC for two physicians and am being told that whatever I paid (more than 3k) may not be refundable. I am a bit stuck. Reached out to managers at AC and they are looking in to at least providing with a more stable Beta 11 AC. Will wait until summer to decide.
