Actually, I was in Harbor Freight the other day, and I saw that side sledge thingy in their percussion section, though I didn't ask about the price, so I couldn't tell you about that. The hammer with the long bill is, however a must have. Note that you don't use the hammer with the long bill as a hammer. Think of it as a drift pin with a handle. You hold the long billed hammer against the pin, and hit it with the BFH! Allows you to control the point of impact better and worry less about flattened thumbs!
