I'm almost done with my hybrid (00' KDX220 engine in an 01' KX125 chassis). I can't give you riding impressions yet, but I can tell you about construction. It's not bad. 
ebecks wright up on this forum is pretty comprehensive and there where only a few clarifications needed during the build. One item to note is that you really need to do your own measurements when it comes to cutting the swingarm. The ones on the diagram posted here are very close, and would probably work just fine, but I'm kinda anal about this sort of thing and found that not only where my parts a little different from the figures listed here, they where slightly different left-to-right.
I used an 01' chassis because I found one with a license plate, and because initially it looked to be the easier conversion (common front head-stay).
After watching art5 and ebecks 03' bikes come together, as well as doing my 01' I now believe that the 03' is the better bet.
Here's why: The 03' seems to have slightly better chassis geometry. Also, the gas tank is shaped differently and doesn't drop down in the rear like the 01' This means you've got a lot more freedom for a large tank without excessive re-shaping of the plastic. (this makes me a little nervous). Oh, and there is much greater aftermarket support for the 03' KX125. For instance, the trick promotobillit kickstand on ebecks 03' bike isn't available for the 01'.
Just my two cents.

Yeah, definitly measure your own swingarm. The diagram I have is reference. I have e both, th e03 definitly turns better but the 02 is more comfortrable. The 03 is also harder to do than the 02 though.
If you were gonna do this and hada access to 03+ parts I'd say do that. 99-02 parts are easier to get though. The 02 still makes the KDX feel old and slow. It is no slouch, it is just that the 03 is a substantial change from the 99-02. Those were really a freshening of the mid 90's bikes where the 03 is completly new.
Remember the 99-02 KX125 won championships.
