I just checked Cheapshotsau on the 'bay, there's not much difference between all of them. Foma's cheapest (obviously), but then it's a tight bunch between TMY/TMX for $36-38 (same as vanbar), FP4/Acros/TX/XP2/D100 $39, and Ektar/D400/Portra160/PanF $41-43 (cheaper than vanbar). All for 5 rolls of 135 and/or 120, so that's $7.20 - $8.40 each (although PanF/D100/XP2/D400 are all up at $48 in 135, but that's still way better than vanbar).
Still, for me, it's much of a muchness between the whole lot of them, these prices don't differentiate what I buy.
(and yeah, B+H is always cheaper, $25/5xFP4, but the shipping isn't worth it just for film. I always throw in a few rolls from there when I'm buying gear/hardware or paper though)
