I have a chance to either trade a guy on caraiglist a TIG welder of mine for a Laguna LT18 and he throws in $1500 as well. I have another guy wanting to give $2500 for my TIG welder. My initial plans were to purchase a Grizzly G0513X2 and a G0690. The $2500 will just about do that. But if I go with the guy with the Laguna LT18 That will just about work to...The Laguna is said to have less than an hour of run time...Any thoughts?
