Every TD will be able to get one if it's in production, just ask the one you prefer. You won't find good Chimera (only with quartz movement) and not sure if Flightdeck is still in production. U-42 and U-1001 should be available. Here they are on Toro's site but you can get them in various colors:
I highly doubt you'll find it. It's uploaded on PT website back in 2008. Don't think they still produce them and I haven't seen any around here for a long time. I know there was some talking about Flightdeck with carbon dial being out of production, not sure about others. But as Tako said, send them an email and you'll find out pretty soon.
As for 7750, it's good movement and almost always used in chrono rep watches (together with 7753). For me not as good as 6497 or 2824 but good enough.
I have ordered 3 Flight Decks and 1 U-42 from Mary and Rochest, but if the items are still out there on the market, Toro or any other TD will be able to get them.
