I finally purchased my plasma cutter, $1450, for a Miller Spectrum 375,new in box.I could of bought one for $1100 but would then be put on a waiting list ,and they are SLIGHTLY used. It' cut's best 5/16" ,3/8", and quality cuts still at 3/8 to 1/2",and will still make it through 5/8".I could of found one of a different brand ,but I have always felt comfortable with Miller ,even though I think I paid a little extra for the name.
