The Sun-Star Stitch Lock Stapleless Stapler staples up to 7 sheets of paper by creating a punch and loop in the paper itself. The Sun-Star has beautiful sculpturesque looks in an all metal construction. This Japanese gadget is a modern take on those early 20th century paper fasteners. The Sun-Star is $34.50.
If you want to start using the environmentally-friendly stapleless system but spend less money, there's a less stylish but just as functional version at Uncommon Goods for just $10.00
