I know this has already been mentioned on other threads but I thought it warrants its own on the Super 8 one. You can pre-order 3 rolls of the new (as yet un-produced) Super 8 film from Ferrania by pledging on their KickStarter here:
The only downside is that 3 rolls is the maximum you can get at the moment as KickStarter limits you to one pledge.
As much as I love the latitude of Vision3, I'd love to start shooting weddings on reversal stock again and this looks like the best bet for the future. They've even talked about their hopes for producing a 400 ISO and a 800/3200 ISO film in the future too, they need our support!
