DevonThink and (what?): Bookends, Endnote, Papers or Sente?

Added later: I would now recommend Sente 6 over Endnote X3. I had a 4-person collaboration and one had an emergency trip out of the country. I had his paper, but many of his references were incomplete and the deadline was looming. I had gotten the Sente 6 upgrade, but hadn’t used it yet. I did need a bit of help, but that went quickly and smoothly. I imported my Endnote file, used Sente’s reference search capability–which was spectacular–and in a couple of hours was able to integrate all the references and send the manuscript. Although I expected that I’d re-import my references to Endnote after my search, it was such a pleasure to use Sente 6 that I’ve stayed with it.
