Which Mig welder to buy?

Learned on a Little Lincoln SP 125 with 75/25 gas,on bodywork. "Borrowed " a high end 220 Lincoln fifteen years ago, to box & notch a 70 El Camino for a BBC cheapo oil pan. Hell my miniscule welding abilities looked decent,with a welder like that. 220 if possible, 110 with argon/CO2 is small & versatile, flux core is time consuming,(& a P.I.T.A...), buy a name brand welder... Coming from a guy,with minimal MIG experience: The better welder you buy, the better your work turns out,the less frustrating moments you have.
