At current count I have four non-SDS mains drills - 2 x110V, 2 x240V; only one of them is ever used and that's got a permanently-affixed Axminster angle drive on it. Just not needed, the rest of them. I wouldn't throw them out though, because some day, I will need one of them. The two Hitachi 110V ones are tough old things and just out of interest I'm keeping them around.
