i would say go for the graphite... i have a graphite
<no time right now to compare my graphite with my friend's DX US on video, but its clear that $100 is worth the better screen and refresh rate>
will do something similar in my youtube channel between the graphite, DX US and Kindle 3 (when my K3 arrives
)

so far, AFAIK, the graphite and DX int'l has the same firmware/PDF program
