Thank you for sharing this resource. The more resources available to people when considering an expensive purchase the better.
I highly recommend people going to a Sew Expo and trying as many machines as possible. Also checking out local places where they can rent time on a LA. There are many communities with rental programs available and it is a great way to see if you can physically manage the machine.
There are a great many different reasons people purchase LA machines, just as we all have different budgets and different physical abilities.
I bought a second hand machine and love it.
