1. there are three styles of cans - which one do you need?
2. Since you need a can and some other parts - find another machine on craigslist in your area - or maybe goodwill. Online - If the seller knows what they have and lists it correctly, it should sell for $100 + (just the can), in two years I've only seen a few come up. Most people get the machine dirt cheap, and then whine when they find out how much they are going to pay for the can - but the machine without the can is only worth the parts on it.
