Kindle or Nook?

I'm trying to decide between a Kindle and a Nook. The Nook seems to win on all issues important to me, but, and this is the biggest thing against it: it's not available locally, and I can't get it even with a credit card because it only accepts US billing addresses. (the second biggest issue: I'd have trouble exchanging it in case I ran into warranty issues)

I can, however get the Kindle. My biggest reason for avoiding the Kindle is that it doesn't support epubs. And yes I know that I can use Calibre to convert, but that's a bit like telling me I can run a program by compiling it from source. I appreciate the possibility is there, and sometimes I may even want to use it, but I don't want to have it as my first step. (this is the same reason I avoid DRM'd ebooks)

Besides, I'd rather support the book publishers selling epubs already, and then just drop it in, not have to fiddle with dog-slow conversion each time.

But my issue now basically is: international support or epub support? And if I get the Nook can I use it without registering anyway? And if I get the Kindle, will I ever get past my annoyance at its nonsupport of epubs to ever use it? Which is the lesser of two evils? Oy.
