I’ve been really disappointed with recent dewalt stuff, I find it heavy and clumsy to use, and you can get stung with non-EU market mexican made guff if you buy online. Only worth considering if you have small hands, as the battery design allows for a smaller grip.
Makita and Bosch stuff has always been good value for me, even the cheaper green bosch stuff.
With the newer Li-ion batteries on the scene the older technology Ni-Cad and Ni-Mh stuff is very well priced at the moment with either higher amp/hr batteries or more batteries then you would have got in the past.
I generally lean toward Makita stuff, maybe its just what I’m used to but I find their stuff quite controllable, certainly more so than Dewalt. Screwfix’s own brand "Site" tools might be worth a look – made by Makita, seemingly with their older technology and very keanly priced just now. If you’re not using drill drivers an awful lot they might be worth a look.
