I have Medisoft as well and am happy with it--but use a third party company to provide customer service/tech support. I also purchased the Medisoft/AC interface for HL7. As other users have pointed out, don't bother with the X-link interface. I am still in the process of getting the interface set up. The documentation explaining the process is totally inadequate, so I would not recommend that you try to do it yourself, but ask someone at AC tech support to help you.
