I beg to differ, Tyremen in Hull will do 4 wheel for £30 providing they have the alignment specs. Might be more for 4WS with 4 wheel drive and laser alignment though, they did my standard GTS 3 years ago (with Hicas but just RWD) for £10, and were grateful for the aligment settings I provided them with.
Never had to touch the setup again and it's been perfect.
