I am moving, and sadly I cannot take my piano with me due to weight and space limitations. I thought about getting an electronic standup just to keep my chops up, but there is a surprising dearth of information online on the matter. Does anyone know offhand whether there is an appreciable difference in weight between electronic and acoustic stand-ups?
Yes, there is a huge difference between an electronic piano and an acoustic. You can find a nice digital piano that ways 50-60 pounds nowadays and sounds great. Here's a resource that I found to be helpful for information on digital pianos. https://keyboardkraze.com/best-digital-pianos/
