I think you're between a rock and a hard place.
I doubt KEH will give you what you want, especially for the case. And most buyers would buy from KEH if given the same price.
CL can work well, if you're in a big city. You do have to endure spam, and might have to wait a while.
That leaves Ebay. I wouldn't worry too much about packaging it. You'd have to ship it to KEH as well, right? Just get a big box and lots of peanuts.
Or, you just write off the $300, take a few shots when you can, and consider each keeper you get to be priceless. Then, you actually profit on the deal. ;-)
