I wish I could take credit for this one, but our heatsink supplier (Ascent www.ascentusa.com ) sent some of these to us free. They are made by Kobalt Tools and called a tack claw. They look like a minature pry bar attached to a screw driver handle. Price $3.98 on Lowes' website here is the link:

Try one of these!
