my hand held is a 10 year old hypertherm 380. works awesome. I don't try to cut anything bigger than 3/16" with it though. My plasma table runs a Thermal Dynamics Cutmaster 51. That is an impressive unit. it will cut 1/8" plate clean @ 60"/min and 1/4" plate @ 32"/min. 1/2" will slow it down in the 12-15"/min rate. 0 problems with either unit @ 10 yrs and 4 yrs repectively.
