Just a quick heads-up for anyone who's always wanted to turn their wall into dust but has been put off by the price of wall chasers: local Aldi had them reduced to =A319.99 (from =A340, I think).
Don't know whether this is national or just certain branches clearing stock.
And I haven't used one, so I can't say whether they're any good or not
- but I've had a 9" grinder and small table saw from Aldi and they've both taken some hammer and are still going.
