i have a zt301 and love it. The only difference is the colors. The 300 is black, 301 green, 302 tan. Its an assisted opener, you simply the push the flipper down and as soon as its flush with the top of the handle, the spring takes over and opens the knife.
I feel this knife is one of the finest values out there on the market. You get titanium handle frame, g-10 scales, s30v blade. These fine features are the staple of crk, strider, hinderer costing 2-3 times more.
As far as where to get one, i would stear away from the $200+ price and get one from kershawguy here on the forum. I got a blem for much cheaper than the $200+ price and i am still looking for the blem.
The only thing i dont like about it is the recurve blade, i just wish the bottom was flat. The recurve just maked it a little harder to sharpen on the flats of the sharpmaker is all. Using the edges of the sharpmaker easily fixes this though.
Its a great knife for a great price and is certainly a great value. I highly recommend it to anyone that is thinking about a top of the line knife, but is a little short in the pocketbook.
Here is some pics i had, not sure where they came from...enjoy !
