I LOVE my A1, but like others have said, drive them all and find what works for you. When we bought out machine, we chose the A1 in part because of the hydraulic lift - there were three of us using the machine and there's 6" difference in our heights. Knowing what I do now, I'd insist on a hydraulic lift and ergonomic handles even if I were going to be the only one on the machine. Moving the height an inch or two up or down can save your back. Movable handles can also help with fatigue.
As for repairs, I've had the machine for over 4 years, and have done all the maintenance and can do the repairs if/when necessary. My dealer is the BEST, and even if she's not right here, she can get me through anything.
Good luck in your search!
