I didnt think anything used Ni-Cad batteries these days
Yep, it's big heavy NiCad batteries for big tough building workers who climb up scaffolding in sub-zero conditions, and lightweight li-ion batteries for limp wristed weekend DIY mouse-pushers.
Nah .... only joking, although there's nothing much wrong with NiCad batteries imo, and DeWalt still make perfectly good tools which use them, though Bosch seem to have gone for li-ion powered tools in a big way. I certainly have no plans to replace my two 14.4v NiCad Bosch drills, and should the need arise, I would consider replacing with simular - if I got a good deal. Despite the fact that I also have a li-ion powered Bosch driver which I am extraordinarily pleased with......different tools, different jobs.
And yes, I've also got the Hilti 36v ...... and the Bosch 24v SDS. Although I wouldn't recommend the Hilti 36v as imo, it's over-priced and new batteries are just silly money. However, the Bosch 24v SDS is an excellent tool imo. Having said that, unless there is actually a good reason, I only ever use corded SDS drills.
The Dewalt DC740KA with NiCad batteries sounds ok to me.
