I have a Smith and Wesson tritium watch. It's sold from Big 5, and occasionally goes on sale down to $65. Not nearly as bright as the Luminox (though I've never held them side by side), but still very bright.
BTW, reading about the Maraglow watches. I had one of them before my S&W, and it was GREAT. Light weight, and a rather brief exposure to light would work for hours. By brief, I mean holding it to a lamp at home for 30 seconds or so. Being readable in the middle of the night, 5-6 hours later.
Easy battery to replace too.
