If you do decide to buy a plug spinner later on I highly recommend this one,
http://www.lockpicks.com/ProductImages/d10-pgs-300.jpg . This is the one I use for home and for work and it has never failed me.
The only problem is that it is super strong so if the plug is attatched at the tail piece to plastic parts in the lock like on a Schlage F-Series knob lock you can cause damage if you wind it up too much.
Otherwise this is a great tool. You'll never need to buy another plug spinner again if you get this one.
