If it is easy to use and makes your life better, it may very well be worth it.
Initially I was turned away by price as well (MD-HQ is $250 a month). But then I realized that with everything it did for me, it was well worth it. I save more than $250 a month in my own time (or the staff I don't need to hire) for my patients to be able to message through the portal instead of call, schedule their own appointment, view lab results on the portal, etc. Even just having the billing integrated saves me tons of time. Or the fact that the faxes are integrated into my workflow so I'm only using one platform for everything instead of logging into separate ones. And that my notes are super fast to type with the chart parts/templates. Anyhow, when deciding, make sure to consider all the time you're saving.
I used Practice Fusion for about a month before realizing it just wasn't going to work for me. I used a different EMR for another year or so before realizing how much time I was wasting. That's when I decided it had to be completely integrated and with a robust portal that all my patients could use on their phones. I posted on a group I belong to for private practice physicians and a non-DPC doc raved about how much time she saved with MD-HQ and since time is money, that made sense to me. I found that it worked how my brain works (very important that you find one that works for YOU). Then I sat down with every patient during an appointment and taught them to use the new portal if they hadn't figured it out on their own. It was simple and intuitive even for the less-tech-savvy when I did it with them for the first time. And now it more than pays for itself. I had two bad months this year of patients falling apart (apparently) but now I'm back to almost no phone calls, everything goes through the portal.
So yes, it can be pricey getting a good one but if you make the right choice and choose something that saves you a ton of time, it will be worth it.
