For a 1.2, there really isn't a lot of point spending a lot of money on it, as said above - if you jsut want to make it go a bit lower, get the TA-technix coilovers at £250 a set, I have them on my 1.4 and they're great, yes the ride is a little bumpier but, I got them for about £220 quid, bargain.
There's also the option of refreshing the OE shocks with lower springs, that'll bring you down a little and won't totally compromise ride comfort.
