Very similar to what others have mentioned already, I made a tutorial that shows step by step how to make foam panels and then you could carve the foam to make them stone-like if you wish: http://www.halloweenforum.com/blogs/terra/1098-faux-steel-haunt-panels-tutorial.html
I think sound quality is the most important when choosing controllers. I've tried a few that have less than CD quality and the sound is disappointing. I've stopped making props for now but if I was to start again I've really had my eye on the BooBox Flex. Not crazy expensive and you can program it using a computer.

Do notice that the lady itself looks a lot like my version of the girl. Must have seen a picture ;)
