I chose an Innova after learning to LA on an unregulated Nolting and then renting time on the Nolting and then an unregulated Gammill (at my then LQS). When we moved, I couldn't find a place to rent a machine and we now had room for a LA, so I started shopping.
I tried the HandiQuilter, Tin Lizzie, and some other brands. I was referred to the Innova dealer by the then president of the new guild I joined and fell in love with the Innova. It is so low maintenance (I can do most of it myself) and lighter than most of the other brands. It is made in Texas. They have 24/7 tech support and it is pretty easy to upgrade and make additions to it.
However, as others have said, shop around and try the different machines yourself, because not everyone likes the same machine. Also, once you decide, check for deals (sometimes there are special package deals) and also look for demos and used machines, such as trade-ins.
