I need an angle grinder for very occasional use, initially to trim some
slates. Any recommendations? Screwfix have a basic-looking Energer model
for an amazing £17.49, with a Bosch at £34.99 and an Hitachi at just under
the £50 mark (the only one of these which comes with a disc). Toolstation
have a Makita with disc at £54.72. There is a Lidl fairly near me
advertising their Parkside 2000W model (no disc) at £34.99, but it won't be
available until the 4th of May and there doesn't seem to be a way of
checking local availability online anyway.

Price isn't everything but obviously I don't want to pay more than I have
to. Many thanks.
