You are right about it being a huge investment! I already have a great machine too and I worry about selling mine, and then being stuck with something I'm unhappy with. I think Innova's are fantastic machines. I think really most of the big names out there are pretty good machines and there aren't too many I wouldn't use. I just have narrowed it down to APQS because I have one and know I like the machine and company, and HQ because I like the machine and there is a dealer local.
Thank you so much for your input and anyone else I'm grateful if you have thoughts to share. While I know that the decision is mine at the end of the day, hearing others experiences really does help me.
