Good source for "new" 5.25 and 3.5 inch floppy disks?

[Warren Ernst <wernst@gmail.com>]

All,

Well, I made up some disks for someone recently, and I was forced to
open my last box of blank 5.25 inch floppies. Uh Oh.

It then occurred to me that my supply of Double Density 3.5 inch disks
is all down to old PC disks, about half of which test bad when I
format them.

Ditto for the High Density 3.5 inch disks for my SuperDrives, which
also test bad about half the time.

So really, what it seems I need is fresh supply of floppy disks, but
are there such things any more? I see folks selling them on ebay, and
Google turned up a few places (such as http://www.oldsoftware.com/disks.html)
that seem to have some supply, but perhaps my fellow CSA2-ers can
recommend a place that has sold them consistently good media at a good
price.

And are truly new, quality, double-density 5.25 and 3.5 inch disks
even sold anymore?

Thanks,
Warr
