We have the old version of it too but I have this setup and my only criticism is it loud as fuck. The only version still gets used and has never let us down but I just needed a new set for my van.
Unless you are doing really wild shit (like putting a cat flap through a solid wall) then I suspect you just need new / better bits if your current drill is struggling to get through masonry to hang a picture frame or some shelves.
Also on the do i need a better one, I had the same with a grinder recently. Had a perfectly fine plug in one I used and could use but had to have the new battery one.
Hammer drills, do I need a better one (I suspect so).
I have this.
