ordered one last night. noticed the changing qty's and prices too. looked at the link and thought it said $82, but when i went back later, it said $87. then i checked it later in the night and it said $82 again, so i figured, wtf, you only live once.
searching similar items, i did find a few of them cheaper, but when you factor in all of the accy's this one came with, still looks like the best deal.
one question, what are the "tr-21" and "tr-23" that come with it? i was assuming they were ac and dc power adapters, but judging by the previous comments, i no longer assume that.
