i use the chisel stop feature quite alot but nowadays only for light chiseling.
bit of channeling, some tiles of walls, removing some bricks etc.
if i am stripping a load of tiling or knocking down a brick wall i use a cheap jcb sds corded and i trat it like a slave.
i have seen the drill in your link and thought about it in the past but it would only end up doing what my cheapy does and that one is doing the job perfectly well.
if you are itching to buy a drill i would recomend a cordless sds. you will not be sorry
