I almost bought one instead of my Gammill: however, the deal killer was that the shop expected ME to take it home, set it up, and educate myself on it while they banked my money. With the Gammill, the sellers were with me all the way; they brought it to me, set it up, instructed me, didn't leave until I was as comfortable as I could get with it and have continued to support me to this day. They also offer free classes but I have not been able to get to them yet...but I will.
So, I guess what I'm saying is that there is a LOT to consider when buying a LA, not just the kind of machine...
