I have noticed that all the drain valves I have seen for sale are brass. Is it possible to solder these rather than using a compression fitting? If so, does solder-ring v. end-feed make any difference?

No.
Yes. Brass solders easily.
Solder rings are easier. End feed look better.
Christian.
Remember to take out the "rubber" washer before you solder the thing on.
Clean up with steel wool and flux, just as you would copper.
Suggest you unscrew and remove the guts whilst soldering. At least, I do, as I rather suspect the rubber parts will not survive otherwise.
Brass fitting are easier IME experience to solder than copper as the heavier metalwork makes for a more even and consistent temperature when soldering.
