Look at is as buying a new car. Test drive each one you can get to. Make a list of what you like and don't like from each machine. Don't get in a hurry. After you have drove a few machines narrow it down to 2 or 3, sounds like you already have. Attend a show over several days and keep test driving. The one you keep going back to the most is the one you want. Some people like Chevy, Dodge, Toyota or whatever, just like APQS, Gammil, HQ, etc. It is all a personal preference and it is a large and nerve ending experience. I got more jitters of this purchase than a new car. Everyone will tell you theirs is the best, because it is a personal preference.
One you keep going back to that one, quiz them on their service and who is nearest to you!!! This is really helpful if you like two equally. If you like them equally go for customer service and support.
Personal opinion here folks.
