The best money I have spent on tools is a milwaukee portaband and a dewalt 4 1/2' Angle grinder. the portaband CAN be chucked into a vise and used as a vertical saw but is best and safest when the stock is held and the saw moved around. The grinder is very multipurpose and having a good strong one for the most common operation, usually grinding, and filling in with HF cheapo's for cut off, wire wheel, flap wheel, fiberdisk and more.
A drill press would be next inline with a MIG right behind it.
