I should be getting an HD100 loaner on Tuesday for some comparison tests I'll be running on Wednesday -- can someone tell me where to find the manual online and anything else I can read to get up to speed in a hurry for this camera? I've handled one once before so I have a basic idea of what to expect, but any tips or tricks would be much appreciated.

Looks like you blew right past the download link, it's a "sticky" near the top of this forum:

Oops, thanks. You can delete this thread if you'd like...
