i've been using the Summit set for years & haven't had even one go bad on me yet & i use them quite regularly. i've put on prolly a hundred or so quarter skins on many rusty old hot rods with them. sheet metal screws just warp & twist the panels too much. the pic doesn't show it, but my set (same one) has the rubber handles too. they're only $19 for the pliars & 25 pins. also, here's a link for extra pins too...
