My shredder crapped out not too long ago, after a long slow decline, and while shopping I was amazed at how much money you could pay for a shredder if you were so inclined. After doing some online research I went with this one which at $64 seemed to be at a reasonable spot in the cost/performance curve:

This is a pretty basic shredder with a stated 11-sheet capacity. It will cut through staples and CDs but apparently NOT credit cards. I think it’ll rip though an unopened envelope with a few sheets, no problem. It’s also much faster than my old shredder. So far so good.
