I would recommend just buying the Victor setup and be done with it. Their portable unit is around $300 but comes with one tip, cutting attachment, and the tanks. I try to stay away from cheap tools because in one way or another they often become dangerous or break. The last place that I want cut corners is with torch setup. I have seen the Lincoln setup at Home Depot which is basically the same setup as the Victor but also about the same price. I would just shell out the extra $30 or $40 and get the Victor setup.
