is buying a welder is a nice idea?

[HiPSI]

those look to be wire feed only, and frankly trying to get a clean weld out of a gasless wire feed is a pain in the arse. spend the money and get a decent one that actually uses shielding gas. i bought a lincoln MIG on ebay almost a year ago, it was a factory remanufactured unit and came with a spool of wire, gas regulator, a cheezy mask, the mig gun and lots of manuals/videos on how to use it (still haven't opened them). i think i picked it up for about $400. the model number is SP135T and it works great. i've made intercooler piping, a full exahust system, welded a roll cage in a friend's car and countless other subframe braces and suspesion parts. but i would highly recommend having one.
