Thanks for the replies. Sorry for the delay, 'hadn't noticed that the thread had come live again.
Yes, that's the one. Have Bookmarked it for later.
Well, it seems that the B&H one is gone anyway...just as well it seems. there was one in Austin, at $190, on Craigslist but I'll probably let that slide.
I have just got the Canon XT here on loan to compare to the D50. Probably post on the other forum if it's still live, so as not to use too much bandwidth on the computer section.
