Yep, I've tried the Gators. I had three punctures on the way into work one morning (turned out to be a tiny shard of glass embedded between the tread and inner wall so it was undetectable by the roadside, but dug itself into the tube as soon as the bike hit a bump), and went to the bike shop in the village at lunchtime to get a tube.
They talked a good game and sold me a pair of hamster skins (to be honest I probably was moaning about punctures) as well as a tube, assuring me I'd never get another puncture. I put up with them for nearly a month - far and away the most unpleasant and unresponsive tyres I've used. One puncture was all the excuse I needed to take them off the bike, and the bike felt completely transformed with new tyres (cheapo Schwalbe Luganos, which shows just how bad the Gatorskins are).
Oddly enough I replaced the Luganos with Conti Ultrasports on that bike, and they're superb tyres for the money; roll very well, nice ride, and only one puncture in the last year.
