In reply to Lynsety:
I've found the cheap 15 quid shimano pedals very easy to get on with after being a bit worried about trying clipless for the first time on my new road bike, they're easy to get in and out of with the tension screw backed right off, and have a bit of movement for your foot to rotate slightly, have tightened the tension a little bit more now I have used them on a few rides.
having a bit of a practice clipping in and out on a quiet, flat road is a good plan, but you get used to them very soon.
