a circular saw and saw guide. You can get a very respectable circular
saw like the Skil for about the £80 price point and then either make a
guide with a batten or buy one like Axminster CE51.

Axminster have (or had) a deal on at present; a Skil circular saw, a Skil
SDS drill and a 4.8 volt Skil driver all for £99:99! You could do a lot
worse than that.
