Take a look at this. I'd pay $20 with ship. I don't think I want to pay more than a third of what I paid for my SR60 but I sorely need one before the padding gets shredded from putting it in my backpack.

If you know of something else, point me the way.

That bCase is fairly popular and it comes up on ebay regularly. $20 shipped sounds good to me.

Alternatives are the headphone bag by Goodcans.com. Depending on the size, it'll run you about $21-25 shipped. I have two large ones, and they fit Grados fine. I wish the bag was a little longer as my AD2000 just barely fits.

I also have a headphone case by Headroom. I haven't tried it with anything else other than my HF-1. It's rather expensive, but I picked up a used one for $20 or $25.
