I have the HF Mig 100 which is a flux wire welder. for the $120 I paid for it, it's great, the wire does stick sometimes but just release tension, back out wire a bit and put the tension back on and volia, fixed. people may say they suck, only because the torch is hot at all times, and with true MIG, gas flow is controlled with the feed trigger, you could start a weld with no gas and get a mess.
