I have an A1 and LOVE IT!! I just added a Compuquilter to the set up, and I really wish I'd done it sooner, but NOT at the same time I got the LA.
Take your time, go to the big machine quilting shows - MQX, MQS, Innovations, Quilting with Machines - to name a few. Drive them all, then drive them again. What is right for one person may not be right for you. This is a big investment, and not unlike buying a car. Decided what features you need. I would not be without the ergo-handles and the hydraulic lift. Just an inch or two change can make a world of difference on you back.
