I have the 4000 and am impressed with what I can do with it. Punching holes is so much easier than drilling. I got the 8" break with mine and it makes bending a breeze. The only thing I wish was different is how it cuts angle iron. When you cut angle you lose 1/2' every time you make a cut. It basicly makes a double cut and you end up with a 1/2" wide slug. I talked to MetalPro and they said it had to do this to keep frpm distorting the angle. You may want to contact MetalPro direct and see if they have any demos. Mine was a demo and got it at a good price and got them to throw in the break.
