Ditto going to a local dealer. You'll get support.
If you do go to several local shops besides taking notes on the machines, take notes on the personal. Hired help usually reflects management's attitude.
Take note of the stuff on display. Do the bags looks like they're new or have been hanging for years? Something may be wrong if they don't have turnover.
Ask about classes. My dealer offers classes on learning about your new machine. i can call and ask questions anytime if I need to.
Do they have a relationship with a repairman? Looking up an unknown in the yellow pages can be risky.
