I just checked with the seller, those aren't the Extended Range versions. Good find, though.

Just wanted to update this thread - there's a source on Ebay with five units remaining at $40 a piece. Super good deal. I bought one as a spare since I already have another. I have not seen ANY other sources, so.. now's the time to get one if you've been struggling to find one.
