I found a supply of 8x10 Acros 100 in 8x10 for a pretty good price at Megapearls Webshop in Japan (Dead Link Removed). To my knowledge, this has been unavailable before. I shoot 5x7 but cut down the 8x10. Dirk Rosler is very helpful, costs are reasonable, exchange rates are good, and shipping is reasonable. (I have no relationship with the vendor).

Look at Tuan's 5x7 article on LargeFormatPhotography.info (http://www.largeformatphotography.info/5x7.html) I use his method: a Rotatrim Mastercut paper cutter. Not cheap, but it seems to work.
