Dewalt for me, Ive always been a fan, from Black & Decker Professional range to ELU to DeWalt ( all owned by the same outfit )

ELU were very good drills, the best by far imho

ive owned Bosch aswell and that was trade qaulity and abused like hell ( it was a 9.6 V cordless )

Dewalt has become very affordable in recent years, my first 14.4 V Dewalt Drill cost me £480 crazy money, screwfix always have them at good prices
