If you get it you should tell nobody. Once they learn it plugs into 120vac *everyone* you know will want to borrow it for a little project.
The nice thing about 240vac machines is that your friends likely won't have the hookup for it, or if they do, they already have a more serious machine.
As far as portability, great if you have a manufacturing plant and need something that can go *everywhere* in the facility without question of power. But are you really going to move it from your shop with the gas bottle attached? An extension cord is likely not heavy enough, you should resolve that issue with the appropriate outlet (& wiring) next to the garage or man door. Argon shield gets blown away with the slightest wind.
Also, the capacity of that unit would be 1/4", but you will not get a weld reasonable enough to join that thickness of material by butting up two pieces of 1/4" plate. You will have to back-bevel the joint (meaning grind the flat edges to a thin "V" edges) and then go wide-open-throttle on the amperage, on both sides.
Can be done but don't forget about the large amount of prep work that an undersized machine requires. In general, in welding, you want to be at the point where a glowing ball of molten metal is about to fall on the floor minus about 20 amps. That's just a euphemism that you want a *lot* of heat.
My vote is no, look for good used name brand AC/DC stick welders before an undersized mig unless its pure sheetmetal, and it doesn't really do a great job on that. Anything sensitive meaning small or lightweight I'd use either a tig welder or silver braze 56% before I attempted to destroy it with a mig welder.
