FWIW I use cheap bontrager slicks on my bike and in many hundreds of miles on the road I've only had one flat. i think that the lower pressure (i run 60-80 at the most on these, which is their rating [one is a 1.25 and the other a 1.5 simply because that's what was in stock]) helps a lot anyway, whereas no puncture resistance on a road bike is pressing your luck.
