I have a 26" ABM Innova on a 10' frame (that is all I could fit, if I could have I would have gone to a 12' frame).
Pros:
IMO the Innova is the best bang for the buck on the market
One of the, if not the best, frame on the market. It is a 4 roller system so you don't have to constantly adjust the take up roller. Makes no difference how backs are seamed. Solid as a rock with almost no vibration made of aircraft grade aluminum.
24-7 factory customer support (although I have not had to use it, thankfully)
Is not fussy about thread, will take any kind of thread I throw at it.
Not temepramental.
One of the most responsive stitch regulators on the market (The lightening stitch). They introduced it after I got my machine so I don't have it, but I got to test it at the MQX and it was amazing.
Retains resale value, but try to find a used one on the market, you won't. Those of us that have them find no need to trade up, trade in, or sell them! You may be able to get a dealer demo but they are hard to find second hand.
Cons:
Have yet to find one.
