These might be overkill for most guys here, but if you work with sheet metal or build bumpers or anything hefty like that then you must have a good set of nibblers.
I have two industrial quality Trumpf N 500-6 portable nibblers. These cost $3000 each, a few years ago. I'm asking $600 each, OBO. I recently had them rebuilt. They work like new. They can slice through thick metal in a hurry.
