Spot weld cutters

What do you guys suggest for cutting the factory spot welds? I'm determined to take this Duster completely apart in pieces like the factory put it together. I could have just cut it up with a sawzall and plasma, but wanted to take it completely apart "correctly". Never done it before. The only piece thats been cut out is the trans tunnel, that went with the console when I sold it. Other than that its complete.

So back to the spot welds, what have you guys used and suggest?
