I bought the auto darkening blue flame helmet from HF for under $40. It is fantastic; instantaneous on/off. Like Frankdozer I just got to learn that I don't have to nod the thing down. I also bought the 130 amp (I think that is what it is) DC inverter welder for $159 (I no longer see it advertised on their website the smaller unit still is). For the handy homeowner, the welder is amazing; under 15 lbs, DC only, a high duty cycle, and can burn 1/8 7018 rods with no issue. I can also use it on a 30 amp 220v circuit; some of the buzz boxes take 50 amps.
