I did an ebay search for the machines you mentioned. I have only seen a large scale one, but these smaller scale ones look great. If you are handy you can probably just by the book and do it yourself. I may just build one of my own, but I must complete some other projects on my list first. Thanks for the post, as you have sparked my interest in making this a future project.
So, quit thinking, Go get one, and let us know how it turns out.
