Seriously though...in a word - from others. Either The TSD Marketplace or on the bay. Though I did mention those two I found at an antique store.
I got my Canadian E as a purchase in August on the TSD Marketplace. That's also when I hit the bay.
I think my timing was good, but I think there are still some good injectors to be found on there (E, G, HydroMagic, even the Canadian versions) for reasonable prices. The real unique ones (i.e. repeaters) are a bit tougher and the Type D and F are almost impossible to find and their price is approaching 'Fatboy' status.
Part of it is knowing what you are looking for.
Schick didn't get into as specific an identification system as Gillete did, but if you
go here you'll find the best indexing of them that I've found. Find the type you want and note their patent numbers. Then go to the bay and look at postings. Most sellers don't take the time to figure out what they're selling. But if there is a clear enough photo you can see the numbers and figure it out. Or just message them for the patent numbers.
One last thing - don't discount the PAL injectors. I'm going to do a more in-depth assessment of all my injectors (in January, I hope), but after a few shaves with all of them (Schick and PAL) my initial thoughts are that the PALs may be the top contenders for my goal of finding automatic two-pass shaves. (based on my whisker type of course)
Good luck Herm.
If interested, at some point I would be more than happy to loan a few of these to you from time to time if you wanted to sample them.
