Ya these things are like pulling teeth for me if/when I finally decide a purchase is warrented. I got the blue AAT which I've only seen at retail twice and the Magnaguardfighter as of the last few months. Wish this line would just go away personally. Obviously there's only 2 people on this site that collect these so that has to tell you something. I don't even transform these things - just using the crossover line to make up for the lack of Action Fleet.
I have a few around the house, too. They are absolutely huge on the birthday party scene. The kids aren't too keen on them, but I guess I've had some fun futzing with them while I'm watching TV here and there. :shrug:
For a bunch of lame backpack transformations, it's amazing how impossible it is to handle the newer ones without them popping into a million amputated bits and pieces. If I was more motivated, I'd customize up some sturdier joints - but, really, why bother?
