UPDATE January 2007: The jag-stang has been out of production since May 2006. Your best bet for finding a jag-stang these days is to search the used guitar markets like ebay, etc… There seem to be a few smaller online guitar shops that have a jag-stang or two but you will have to do a lot of searching on the web to find them.
Again your best chance is to get one used off ebay.
