Yeah there's a difference between them - band saws use a large blade in a long loop/band that just spins around (the big ones are the Ultimate Saws IMHO). Fretsaws have a small blade that goes up and down and can break easily if you push too hard.
@Oclocker: yeah, that's a great idea! A sticky thread here in the modding forum, a visual tools/stuff dictionary, alphabetically ordered of course... something like this perhaps: Name of the tool / alternate name <-- bold, size = 4 [ image1 ] [ image2 ] ... <-- standardized size, say ~100x100 or perhaps ~150x150 pixels, clickable so they link to a larger image. If there are different kinds, there should be images of at least two versions. _Short_ info text + links to more detailed info. < insert 2 blank rows, then next item > Example: Jigsaw / Jig-saw A very good tool for cutting stuffs ...

Never used one of those, but did see one similar on ebay when I searched for 120mm holesaw yesterday. Couldn't decide whether they'd be brilliant or useless for cutting perspex, but I can imagine it making a real mess if not used extremely carefully.
I remember telling a mate on icq (long time ago) that to test his possibly duff inverter for his ccfl he simply sticks his tongue on pins tingles if live!. Realised daft idea cos he's nae fully electronics savvy imeediate message followed followed by what seemed like forever until he replied (i had visions of his tounge exploding with 800v He never did do it thank gawd..
i'd expect good results IF tool survives setup - & drill used runs nice and slow. May even try it after its survived ceiling/floor cutting!
I actually use my tongue to test 9V batteries Not sure how much of a jolt you'd really get from the output of a CCFL inverter; bear in mind that it's high voltage but at an extremely low current.
When I was a kid I was in my room reading a book and mindlessly toying with the cord from my Atari's power adapter. I ended up sticking it in my mouth -- and the other end was plugged in. Your hair really does stand on end when you get electricuted.
I've used one of those adjustable circle cutters on plexi. It worked surprisingly well, but it was an 80mm hole and seemed like it might be less stable making a 120.
