Hondo, I have the ZT 0200, and I did consider the 301/302 before getting it. The obvious differences, which I'm sure you've seen on the Kershaw website are:
-0200 is 154CM, 301/302 is S30V. Both good steels.
-0200 black/black blade only, 301/302 striped blade only
-0200 G10 w/steel liners, 301/302 G10 w/titanium liners
I did consider both, the two major factors for me were colour and opening mechanism. I have quite a few assisted opening knives, and I love them all, but this is a knife I would take out in the bush camping, where I don't have access to all my tools. If I were to drop it into sand, dirt, or for whatever reason needed to take it apart, I would rather not take anything with a spring in it, I'm not that skilled at it yet. That might change as I play with them more and gain more experience, but for now that was a major factor in taking the 0200. The fact it's about half the price in some cases doesn't hurt either. If you want AO and are taking out into the bush, consider the ZT 0500.
BTW, NGK has them on for $236 (301/302) and $129(0200).
Dann (glockman) should be around shortly to tell you how much he loves his 0200 shortly, along with joejeweler.
Hope this helps, good luck with your decision.
