You say longarm, but do you really mean midarm? The longarms are generally thought of as 18" or longer. Midarms are between 9"-18".
For longarms, you just can't beat an Innova. I have a lot of quilting friends who have upgraded from Tin Lizzie, Homesteader, Nolting, Voyager, APQS, just about every brand out there, and when they get to Innova they stop looking. Only one quilter hasn't switched from her Gammill and I'm pretty sure it's because she spend so much on that setup!
Where in Washington are you? It might be worth the drive to go to Boersma's in McMinville, south of Portland, and play on their Innovas. They have classes you can take that will give you hours to play and practice on the machines, really give them a thorough test drive and check out all the available features and sizes.
