haltec, dfi, hondata, or what?

cool...i was leaning towards the hondata anyway. i was originally going to get the 2B until i recently went on the hondata website and saw that they now have newer systems out (s100 and s200). it says that unless you have a PR3 or a PW0 that you should use these newer systems instead of the older (2/2B/3/4 etc) systems. since i will be using a PR4 i am assuming that i should be using one of the newer systems, but am not sure which one. i think that i am going to end up just contacting hondata and asking them, but i tend to believe that i'll end up getting the s200 b/c its better (although i am not yet sure entirely why this is so).
