I've noticed that Ilford HP5+ is quite reasonably priced right now. 11x14", 25 sheets for $160, not bad eh! $6.40 per sheet.
There is some 4x10" advertised at B&H, but only in special order batches of 20 boxes at $56.50 each for 25 sheets. Anybody care to split the order with me? If not I'll just cut down 8x10 as usual... but it's a nice luxury to have pre-cut stuff in a proper box.
