Go for it
I wanted a long arm for many many years but never had the money or space for one.
When I retired and had an empty bedroom I finally bought a long arm.
I got a Grace Qnique 21 Pro with a 10 foot frame. I love it and can do much fancier quilting on it than I did before. No more struggling to baste a large quilt on the floor and cram it through the 9 inch harp of my sit down.
I
bought it on sale with zero percent interest for 5 years.
Buy it if you have the space ( mine displayed much more of my sewing supplies than I thought) and the money. Shop around for the sales and consider used if you have a way to transport it. For me the appeal of making 0 percent payments and free delivery made new a better choice.
it did take me almost a week to carry it upstairs and set it up by myself. I did need help lifting the machine onto the carriage but otherwise I was able to put it together by myself.
so consider setup when you make your choice. Some companies will come to your house and setup for you.
good luck and let us know what you decide.
