I also use "Regular" sockets on my impact because I don't see the need on spending more money on an Impact Socket. Sure, maybe if I was a real technician I would, but since my work just includes "basic" stuff in the garage on my own time, the regular sockets have been just fine for me. Haven't broke one yet, but if one ever does break, they are like $5+ to replace at any auto parts/hardware store and a lot of them come with a lifetime warranty.
