When I was at the San Diego Quilt Show there was a vendor there called SewCranky. They had some very interesting machines - I admired the machines from afar, and luckily my friends did not encourage me to get any closer. So I cannot tell you anything other than they do have a website, and the website lists their upcoming events, and they have a lot of fun looking machines.
Good luck - post pictures when you find one you like, okay?
