Sam Blasco, a member here at SMC, is your friendly MiniMax/SMC rep.
He's also a craftsman, trainer and outstanding "jig maker". One thing he can do is help you locate others in your area who have machines and will allow you to take a look. They might not have the same machine or machines you might be considering, but it will help you see the quality and so forth and also get candid comments from an actual owner/user. I've had a number of folks visit here who were considering purchases. Other manufacturers, such as Felder, will likely be able to do the same for you.
As to installation...yes, you can pay a fee to have someone install Euro machinery, but honestly, it's not absolutely necessary to do that. Un-crating, cleaning and implementing the machinery is a great way to get to know it "intimately" and there's not all that much "setup" to do, in my experience. For my slider, I picked it up at the trucking company docks (they loaded it on my trailer with a forklift) and brought it to the shop. With some help from a few friends (coffee and donuts supplied...
), it was moved into my shop and put in place. A pallet jack took care of the final placement. (Theres a pictorial thread here at SMC about that)
