appears my first post disappeared, I can't see it. sorry if end up double posting...

I have a mazda3, uses CAN protocol. I am looking for the most flexible CAN adapter, preferrable with USB (bluetoof even better), and decent software (or SDK) I would like to be able to hook it up to a Palm (Clie NV70) or PPC (x50v), winders only in the worst case...

so far I found these:

http://www.dgtech.com/product/dpa/dpa.php#DPA4 (w/labview support!)

can anyone let me know which one is better, which would be most compatible with the software others (on this forum) write, or perhaps recommend another adapter altogether
