^^^^ Id say they are but only if you want a piece of history. A lot of folks up here have extra habs stashed away and they periodically turn up on ebay. I cant see the crazees paying 50-100 for a plug tho. I read here bout the fisher and the dmag plugs they are going for 50 or more. I hope I don't get flamed for saying so but just can't see how a plug for 100 will outcatch a good swimmer you can buy for 20. Don't kill me just my .02.
