Or you could go towards the terminally tarty option of Speedplay pedals and cleats, only 137 quid for the pedals ( cheap ones) 280 quid for titanium and 60 quid every time you wear the cleats out. I use them on my road bike you can play with "float" to your hearts content, I like them a lot you are very definetely in or out of them and i can clip in even faster than spd for those sprint of the lights days.. I use spd on my CX and MTB I find them a bit "vague" . I used SPD-L a long time ago useless for commuting for me I was always kicking them upside down normal riding they were fine. Speedplay just step down and off you go and not much chance of puling out of them. Big warning though, if you get grit behind the cleat spring you will have a bugger of a job to get out of them. Happened to me twice, had to find a soft hedge to stop in. Oh and you either have ot find 4 bolt options shoes which are rare or use a 3 bolt to 4 bolt adaptor which is what most people do.
