I started off with the M324's then ditched them for the M520's so I don't have to try and flip the pedal over to clip in. The M520's can also be found for about half to two-thirds the price of the M324's - so get the M520's unless you really like being able to ride in normal shoes.
Re tinstaafl and pulling straight out - I think you will find you have multi release mode cleats instead of the single release mode cleats. The M324's come with multi-release as standard, the M520's come with single release mode.
Be aware that the M520 pedals have the clip raised and so they are difficult to use with normal shoes. Worse still, there are at least two different pedals with the same name - I've been looking at the things thinking they'd be an advantage. Basically, probably not with what I've seen but it's worth including them in your searches (remember, we seem to have less choice here in Adelaide than Sydney and Melbourne shops).
I wasn't aware of the multi release mode business. That'd explain some of my emergency clip outs and if so, it makes clips with those a definite 'must' over those that don't for normal riding.
