One of the reasons I like hand stitching so much is the portability factor.
However I have used my machine in my travel trailer (parked on our two acres in the woods...power and water hooked up). The only problem I had was that the light was not really good except in the daytime - an issue with hand stitching as well. Yours probably is newer than mine and the manufacturer has addressed this issue...I have an early - mid 1980s model.
