Way back I bought a Millermatic 175. It's a 240V machine that will run either solid or flux core wire by swapping polarity and drive rollers. Solid wire and C25 make pretty welds, but most of the time it gets used outdoors. For that I use flux core. Recently I've been trying to avoid the temptation to buy an inverter welder. It would be fun to have one, but the Miller does a great job on everything. At less than 1/2 the price of a decent MIG welder the inverter welder would be a nice piece of equipment.
My plasma cutter is a Hypertherm Powermax30 Air. Not exactly cheap, but nice and handy. Had a project at church that involved slicing stainless in place. With the 120V plug and a good exhaust fan (hexavalent chromium not good to inhale) the job was a piece of cake. I don't do real heavy work, so the dual voltage and self-contained compressor make it ideal for me.
