s2u2, touchlock pro, throttle lock, pocket shield (pay) all lock your device. They have different settings/options, so you'll have to mess with them and figure out which one works for you.

Edit: Hovthagawd, I've never tried sensorlock (completely forgot about it), but does it drain the battery more than the other ones? Seems like it would if it has to use the accelerometer to lock/unlock all the time...
