Thanks for the replies, guess my mind is made up!
I know the DA40 is not a fair comparison to the C152 but there doesnt seem to be too many schools offering the DA20. Most places are for the DA40 so I'm just thinking about options when (if!) I pass.
Some even offer the Garmin 1000 glass cockpit which has to be the way to go from what I have read...
Thanks again, any more opinions would be appreciated.
