Semi-OT - Sources of magneto-optical disks?

I posted this over on the rescue list, but I figured it's probably close enough for here too, since I use these for classic machines. I'm looking for magneto-optical disk cartridges. Primarily the 3 1/2" versions, I use the 128mb disks for shuffleing data around between old machines, but I actually have a mix of drives - 128mb mostly, but also a 230mb and a 640mb drive. I also checked last might, and found the 600mb 5 1/4" drive I had forgotten about. Just no media for it.

I've been checking on eBay, and they turn up from time to time, and I actually just bought a few 128mb disks there. But mostly, the MO disks available tend to be the expensive, higher capacity disks that I can't use. These old, small ones rarely get listed, and I almost never see used ones. Or, when they do get listed, the shipping is wildly inflated. For example, I found an auction for 20 used 128mb disks. Flat rate $20 shipping. How it can possibly cost $20 to ship a small box of disks is beyond me. Likewise the BIN of $2 for five disks, with flat rate $12 shipping.

So, anyone have a good source of these critters? I remember buying a few boxes many years ago (back when the Zip drive was the great new thing) from an online media store, and paying about five bucks apiece for brand new 128mb cartridges. Surely the prices should have come down, but the the cheapest I can find them is $7 each. I'd really like to just buy some used cartridges, but I guess the used media market isn't what it was, I don't really even see used tapes much anymore.

So, anyone know of a source of 128mb, 230mb, 540mb or 640mb 3 1/2" disks, or the 600mb 5 1/4" disks?
