What I found was with the original socket, if you are stuck in traffic for a long period of time with the brake on, the bulbs get hot enough to start to melt the plastic of the socket and the bulb loses contact (I had one come out inside the lens). If you are not generating the heat to begin with, the "cheap" socket should last.
My plan is to only change the two sockets I had an issue with and if reasonable, go with the better parts to do so, but change the bulbs to LED's as well. Another advantage to the LED's is they are brighter.
