I tried 2 or 3 different ones, got all kinds of hints and tips and tricks (that's why I kept trying), and I never was happy with it. Bought a Woodchuck, and have the pencil trimmer type from Kustom King for when I only have to do a couple. I'd take either of these over the Tru Center. Unless you plan to do a lot of arrows, the pencil trimmer type from KK should work just fine. If you do plan to do a whole bunch, the Woodchuck is a good investment, unless you have a sander and can rig up your own jig.
