To all who have replied - Thanks !
Interesting reading......
I must confees that I purchased a couple of 14.4 Volt "Nutool" drills at about £18 around 3 years ago... I needed one for a job and bought another as a present, although ended up keeping that. I was impressed with the performance, especially of the smooth trigger response, and the torque it produced - it actually snaps expensive Pozi 2 drive bits if you are being a bit enthusiastic. However at about 3 years the batteries seem to be dying and I was having a re-think about a better quality range or maybe I'll just re-fill the packs with fresh cells I have used my brothers De Walt item, but find it has a poor trigger in comparison (jerky steps) and he also thought this Nutool was better, but can't be seen (on-site) with a "cheapo" Nu tool - I don't have any hang-ups like that.
Replies has given mixed reports but I suppose it depends on what you are comparing to what. If you are used to a £200 item, the £75 is likely to be not as good.
I will keep pondering but it seems that Ryobi might be a reasonable compromise for my use
Thanks again, Nick
