for a small SDS like what you are after I like the Bosch and Makita ones.
If you want something for doing some heavier DIY work then in all seriousness look out for one of the large SDS drills from Aldi. I picked one up for £30-35 about 6 years ago and have done lots of knocking down and drilling with it (25mm dia x 1m long bits) and I finally broke it back in January.
I was looking for something to replace it but in the end I called the free-phone number on the drill and the nice German lady emailed me a parts diagram and I emailed her back with the parts i needed – I had stripped the gear on the armature so needed a whole armature, the gear it mates with and a the motor bearing as it wouldn’t come off. The grand total including shipping was £16 and they threw in some more bearings and seals. Drill is back in action.
