Storage binders for big negatives

Hey APUG!

I have gotten away with some basic, black binders from B&H - they snap shut to keep dust out and whatnot.

I am now using these oversized negative sleeves for 6x7 and 6x9 negs, but I am having trouble finding binder options. For some reason, the price jump goes from $11-15 to over $50! I can't imagine that much more value from something so simple, and slightly larger.

Does anyone know of a less expensive binder that will hold oversized negative sheets? Ideally, it would also snap shut. I have considered basic archive boxes, but you can't flip through as easily.

For reference, the negative sleeves:[TABLE="class: specTable, width: 642"]
[TR="bgcolor: transparent"]
[TD="class: specTopic c28 fs14 bold, bgcolor: transparent"]Dimensions[/TD]
[TD="class: specDetail c28 fs14, bgcolor: transparent"]10-1/8 x 11.5" (25.4 x 29.2cm) (WH) ()approx)[/TD]
[/TR]
[/TABLE]

If you go to printfile.com you can find some "box binders" that will work good.

I've always used these. Nice, sturdy, and snap shut.
