Would this SDS drill be OK? - Its £93.98 from B&Q

Bosch PBH 240 RE

Definitely. However, if you aren't expecting to do much work with it, I have
the (now) 29.99 NuTool. It isn't particularly known for reliability, but
mine still works without any problems at all. It even comes with a load of
cheap bits and chisels and has easily given me enough value to justify the
price even if it explodes tomorrow.

BTW, when drilling rawlplug holes with it, I find it best to drill the first
0.5cm - 1cm without hammer.
