Just throwin' in my $0.02 here.
I have Speedplay X2's. They have been great. The coffee shop covers are a must-have -- saves on the wear and tear on the expensive cleats and allows you to walk without sliding (too much) and picking up rocks, etc.
As for the cleats:
I was nervous about how much or how little to tighten the cleats, as I had read all sorts of horror stories on roadbikereview.com. So, I took them to my trusted mechanic, Pepper, and had him adjust them for me. I was amazed at how hard he torqued them down. He didn't treat them with kid gloves at all. Still, I haven't had any trouble snapping in or coming out of them.
I give them a squirt of dry lube every so often - I'm probably overdue right now. Overall....pretty low maintenance.
As for pedalling:
When I first started using them, they felt really strange. Out-of-the-saddle climbs were an experience. I felt like I was stepping on a melting ice cube. I felt like my legs/feet were all over the place. It took some time for me to learn what I term leg-discipline. Once I got over that, they've been awesome.
Highly recommend them.
p.s. For what it's worth, I had Candy C's on my moutainbike - same basic system as the Quattros. I took 'em off. Couldn't stand 'em. I went back to SPDs for off road. Not the same, but just goes to show you...to each her own, and sometimes you have to try different setups to find what really works for you.
