For starters I would book mark this site: www.dvxuser.com
Then I would pick up a copy of Barry Greens HVX book. Last but not least I would pick up another P2 card. I personally would hold off on the E series cards until they have been tested by the general public. With an ESTIMATED lifespan of only 5 years, I'm not sure yet if they are worth the money. If you wait a month or two after they ship, I think the R series cards will drop in price.
