I own both a DP and an acoustic grand. They do feel quite different, but I don’t think there’s an issue with bad habits. If I’ve got something coming up where I’ll be playing someone else’s piano, sometimes I play the DP just to get sense of playing on a different instrument, and it helps me feel more confident that I will be OK on another piano .
What I would recommend is thinking through whether you will actually use the DP. I bought the DP first, and after I bought my acoustic grand, I just find that I enjoy playing the grand so much more. I’m rarely in a situation where I need the silent practice. So I almost never play the DP. However, if you are in a situation where you can really take advantage of a DP, I don’t see any major issues.
