Agonizing over it is completely understandable! It is a huge investment and you want to be with your decision for many happy years. Make a list of pros and cons and look at every feature. Price, the rack, the maintenance schedule, how the dealer treats you, warranty the whole thing. I agonized for almost 2 years before and at least a year after. I am still hesitant to test drive other LA machines at big shows for fear I will love it even more than my Innova! LOL. But I am happy and we work well together and that is all that really matters. Heck I even agonized over upgrading to the lightening stitch while she was at the factory. In the end I figured I am pretty darn happy with my work now and why shell out another few thousand for different stitch regulator when the one I have is producing the results I want? I still wonder if I maybe should have but it is water under the bridge and I am sure my dealer will be happy to upgrade me should I decide to do it.
In the end, I think you can trust your gut. You are already doing beautiful work. I sometimes wish I had the courage to turn off my stitch regulator. I only tried quilting without it once and the world didn't come crashing down! LOL.
