Alternative Q/R hitch for a Burley trailer?

I'm looking for a hitch for a Burley child trailer---the type of hitch was discontinued recently and absolutely no one anywhere on the interwebs has it in stock any more.

It's the "Alternative" hitch (as opposed to the "Classic" or "Standard" versions). I need the quick release version, standard length (126-135 mm). Here's what it looks like:

Anyone happen to have one of these lying around that they would be willing to part with? Now that it's discontinued, if you can't use the standard hitch (because your frame has breezer dropouts) the only option is this ridiculously ugly and clunky plastic triangle of crap that you attach to your frame.

thanks
