I ran Zafiros and ate an inner tube every two weeks (300 miles). I switched to a pair of Schwalbe Marathon Plus and I've gone 2500 miles without a flat. I've heard good things about the gatorskins but a friend borrowed my bike and brought it back with a Marathon on the back; I got home with a wood screw sticking out both sides and decided not to hunt too much more.
My inflators won't get my 700s over 55 psi. However, 700s will roll fine at 55psi. I also carry an alcohol wipe. The optical ones are the right size, they last forever, and they keep your grips from turning gray the minute you have to change a tire.
