Another kit, other than Doug Ritter's that seems to be good value for componants to be used in making your own kit is the NRA kit when it's on sale. It seems, however, that the componants it offers are ones you already have (Blastmatch, tinder, Mirror, whistle). I wouldn't use it as a stand alone kit, but it's a good value if you need those particular componants. The container it comes in is very sturdy as well, though kind of bulky and heavy.
