For a $200.00 price range, you could buy just about any production folder without hitting the semi-custom knives.
Toss out AUS 8 with a spending limit like that, check out benchmade, Emerson Knives, Kershaw's ZT (Zero Tolerance) line, just about anything really.
Find a general shape and style that you like and start buying away. You could also check out the For Sale area off of the main page, usually really great deals there, I'd say about 75% of my knives came from the guys here.
Now, if you want a descent folder under $200.00, I'd almost always recommend a Benchmade Griptilian, but if you want the bragging rights of saying,"I've got a $200.00 knife," then we have an approximate range of what to recommend to you :thumbup:.
For a big beefy folder that says,"krun smash" everytime you open it, then there are kershaw Zero Tolerance 0300's that can be found for $200.00 or less if you look hard enough (I won my 0300 off of the bay for $197.00

).
For a Long but sleek folder you'd want to check out a Spyderco Military, very lightweight and doesn't take up any pocket space. Great materials, G-10 handle and the regular military has S30V for the blade steel.
For a more self defense but still heavy duty knife, there are Emerson Knives which deploy as soon as it's pulled from your pocket (legal just about everywhere except NY).
And for more medium, well balanced knives, benchmade has a wide selection to choose from. My only complaint with benchmade is that their blade stock always seems just a tad thin compared to what I'm used to. IMO, for the price they could afford to add an extra .01" or .02" to their blade thickness.
Hope this helps, J.
