Glad to see you are in the market. It was fun showing you my 19, I know the 17 is better suited for what you are looking to do. Having seen Gerda's Café Egg you can appreciate the 17. If you succeed in your purchase you will join the four current owners and one soon to be owner (eh? Mark) from Wisconsin.
The largest seller of used 17's is Escape Trailer Industries, it is critical to keep an eye on their web site for what they have. They never seem to last long, like hours.
