i've got a source for the blank bands -- they're pricey, though -- $30 for 1,000. just wrote the vendor to see what's what and hope to have info for it tomorrow.
bassdude, i'm getting a package ready for you to go out monday, and i'll toss some of these in for you to check out.
i have some of these, and they're really useful. they're loose (so you can't print 'em) and meant for writing on by hand. they're good quality, though.
i'm thinking 1k is a lot for one person (though maybe not, knowing some of you guys!), so maybe we can group up and divide up a lot of 1,000 bands to cut down the pricetag.
