That is a lovely machine and certainly worth the money. I have a Husqvarna Mega Quilter, same principle. I don't use very often but when I do it just starts up and runs, even with only treating now and again to oil. I've yet to find anything it won't sew and the straight stitch is better than any of my other machines and not fussy, goes from lining to more substantial fabric without any messing around with the tension.
Mine could do with a service as well, but very heavy to move any distance on foot, which is what it would want to get serviced. I think mine cost £350 but it had been used in a business making fabric handbags.
