Boersma's is in Oregon about 4 hours south of Seattle. They are the dealer for Innova and may have used machines or demos.

They also have a sub dealer in Washington State, her name is Capri Beckman. She is very knowledgeable about the robotics and very active on Innova FB group. You may want to try contacting her, at the very least she may be able to let you try one out. I could only find a FB page for her
