Correct about they each have good and bad things. There is no one perfect universal design; one size fits all solution. We all have our own quirks, likes, dislikes and personal comfort conditions. One of the worse things that you can do is put the money out for something that bothers you during operation (seat, controls, etc.). The other sin is buying something that can's do the particular task that you require. Both the BX and the 455 have owners who love 'em, and owners who don't. I don't believe that either design is so clearly superior that it is going to knock the other out of the market. When I took a 4xx for a test spin, I actually liked the feel. But… it didn't have the functional capabilities I desired. So, I went with the BX. Now, I personally don't dislike the rocker pedal (except for when it sticks /w3tcompact/icons/frown.gif), it's just that I like the JD configuration a little bit more. From what I have seen posted though, as far as general ergonomics go, the NH's seem to be the innovator.
