I think my favourite one was a small poker chip case - I think I bought it at Walmart for like $12 including the chips and the cards. The dividers that hold the chips are the perfect size for 1.25" eyepieces.
Another item I've used in the past was a small fishing tackle box.
Currently, I'm using a black bag that is small that came with a Chinese tea set in it, similar to this one:
Right now I'm using some cloth to protect my eyepieces, but I plan on getting a block of pluck foam to fill it in. It's the perfect size to throw (place?) into my backpack that has my other accessories/books/etc.
I've even seen someone use a pencil case!
