I bought mine through B&H in July/August. They were not in stock, but I just placed the order and had them post it to my credit card - it arrived I think 3 days later and was supposed to be over a week.
I've bought like this from them a couple of times - trying to get in on an arrival of order otherwise is hit and miss. I have found them to be quite reliable and trustable in this regard - they come through.
Thanks for the advice, Lyle. I've been using the supplied Semigloss Photo Paper and will also try the supplied Archival Matte Paper next! The only problem now seems to be the colour-matching between the prints and the screen. I've a feeling I'm gonna be having a very busy weekend!
