I've wanted a fisheye for sooooo long, but haven't been able to bring myself to make the plunge (so awesomely cool, but so much $$)
I have a go pro (non hd) but the thing is ridiculously flaky. I'll see if I can borrow one that actually works. I also have a homemade rig for my headrest to use my regular camcorder that doesn't work too bad.
Starting my new job (yay!!) on Monday so I'll find out if I'm in for the longer or shorter version of WitW
