I have been using a 30V cordless "challenge" drill from argos for about
3years and it has served me well. It does struggle a bit when drilling into
concrete lintels.
I am starting work on building a DIY conservatory, which will involve
drilling into concrete and the outside wall to attach the frame.

The amount of DIY I do doesn't justify the more expensive drills, so I have
narrowed it down to 2:
JCB 800Watt corded hammer drill for £29.99 supplied with case and a few
drill bits or Wickes brand 810Watt percussion hammer drill (13mm chuck) for
£17.99

any thoughts coments

kind regards
Bruce
