Yeah, i would say short of stumbling across a great deal in the forums, and youd have to be pretty quick to grab one at $150, $170 is what youre looking at.
But, i would also say, this is an amazing knife for even $200 let alone $170, so, even at $170, youre really doing well value-wise. As others have said, Ebay is a good place to look for a bargain as well.
But, remember, with Blade just behind us and new knives being introduced, the BM has some competition, like the Kershaw Bump and Robo-Dominator, both of which look pretty good to me, though i havent yet seen one in person. Still, it'll be tough to beat the BM for sheer smoothness and quality, it truly is not all that far from a real Mayo, think of it as Miracle Whip....

Yes, the real Mayo is a better knife, i know this having owned a few, but of course the BM can be had for 1/4 the price of a real TnT and frankly, the real Mayos are too expensive and just too damn nice for me to use, so for that reason also, the BM is a good choice, you wont mind actually using it.
