nobody that I've ever found repops them. My take is that they were a 1 year only deal, and non-functional, so the repop market would be a slim niche, making it financially not feasable for companys to tool up for them.
I found a guy on ebay one time with a pair, that looked like he was repoping them. Couldn't really tell from the vague description on his ad. I sent him a few messages, and never got a response, so I guess it was a no.
Only way I know of to find them, is to watch ebay, and they always go for WAY more than I deem them worth.
Good luck, let us know if you find anyone that makes them.
