I sooo wish I had this the other day when I was hand sharpening 6 dozen pencils (still have a bit of a blister)!! And at 68% off retail price, it is totally worth it!! And this particular one gets great ratings too!
X-ACTO Spira Electric Pencil Sharpener– $7.99 (reg price, $25)
Also remember that Amazon prices change unexpectedly, so check current price before purchasing (it might even be lower!)
