You know... I think about 18v drill and impact driver as hammers. You can pay more for a brand that will do the same thing but will hurt more if broken or stolen as they get borrowed a lot.
I dropped my RYOBI impact driver from 24' ladder and it didn't hurt (still works) but if it was an expensive makita I would have suffered.
There is other power tools you wanna have good quality from a performance and safety point of view, like a table saw or a skill saw (circular saw for mr. Right word
) but not impact and drill IMO. Specially if this is not for work.
