Cheap manual nibblers (about $10) work, but are a

And I've broken cheap RS nibblers on thick aluminum... they are OK for
plastic and really thin sheet.
If you've got a compressed air supply, you can
pick up a pneumatic nibbler
for about $30 from your local cheap Chinese tool store (e.g. Harbor
Freight). These can make just about any shape hole in sheet metal up to 14
gauge very quickly and easily.
Ooh... I gots to get me one of those...
