One piece of advice - don't let price play any part of your decision. This isn't just a knife, it is a functional luxury item - much like a fine Swiss watch or an expensive bottle of wine. You can cut with a box cutter, you can tell time looking at a Casio from Target and you can get drunk off malt liquor. Don't lie to yourself because you're looking for something much nicer than a cutting tool. You're looking for something that you can appreciate, something to admire and cherish. Considering that, buy the one you want - the one you really want. If you chose the cheaper of the two based on price, every time you look at it and admire it, a part of you will still be lusting after the other. If you're anything like me, that will bug you more and more and you'll eventually end up losing money selling the one you've got to purchase the one you really wanted in the first place.
I don't know who said it or what the original saying was, but the version I tell myself is "buy the one you want and you'll only cry once." Sticker shock is a painful pill to swallow, but I promise that as the years go buy that $50 won't mean nearly as much as the pleasure you get out of owning something you truly appreciate.
Best of luck with your decision.
