As for punching holes for a few sheets easily and economically - this is the product. Been using it for 5 or more years, with only one problem...The plastic cover over the bottom meant to contain the punched holes slides out of place too easily, spilling holes around and making a mess AND within months of use cracked and became too loose to stay on reliably. Just now a colleague picked up the 3-hole punch and ... little white dots EVERYWHERE. And I can't find a replacement!
