Cheap alternative to machine polishing

[95Aero]

Wanted to get my car machine polished, but local rates (Nottingham) are around £140. I'm not looking to turn my car into a show car, but want to invest some hours in getting the paintwork looking tidier. Can anyone recommend a decent polish / or kit as an alternative to forking out £140? Thread for my car is here: http://www.pistonheads.com/GASSING/topic.asp?h=0&a...
