Don't skimp on clamps. Either take my advice and find out today, or you can just go ahead and buy a bunch of crappy clips that you'll never use because they don't work. The Kreg clip is great. Basically it's a vice with flattened ends to allow for tightening. You can change the clamp spacing by simply turning the adjustment screw/bolt on the bottom of the handle. When used correctly, they hold up very firmly. Now they're a little more expensive than most clamps, but you'll make up the difference in no time! They're not plastic, they're steel. They last a long time and are simply better than most clamps. pull the trigger
