There are quite a number of originals around to be had. Another option might be to either build your own, as many of us do or contract with someone like ProHandyman who builds a nice tear at a great price. That way you get something you fit in, and has a lot of the newer accessories, and is road worthy from the get go. Just an idea.
What you need to watch for is someone with an original, that needs a total rebuild as it's trashed or rotted. If you are willing to do all the work, fine. At that point, you are basically getting a frame, some patterns and a title. That may or may not be what you really want..sorta depends on your abilities and desires. Arm yourself with as much info as you can, and don't get emotionally involved with something. There will be another down the road. Just my opinion. Doug
