My personal experience with the vipercut 30i is great. I mainly cut 14 and 16 guage metal. Have cut 1/8 great also. As for the Forcecut someone else will have to give there opinion on it. Im sure there are bad experiences with both. I would suggest buy the best you can afford. Some things I done this morning This link is what I mainly make with my 30i. Just an example and if you remove my errors its a nice budget machaine to me.
