Hi 65, I think I can chip in on this too as far as the harbor freight welders are concerned, 72blu is being a too critical.

I own a harbor freight 90amp welder and it does it's job, they recently moved to a new manufacturer. I've had the pleasure of using both old and new, the new black ones seem a little better built. It also has a sweet current cut-off when you aren't holding the trigger, so no stray sparks.

Now the question is, how much are you going to weld? Either way you slice it, mig isn't as clean as a argon gas hookup. If you want it to look like perfect, flux core mig isn't your gal anyway. Perfect is the enemy of the good. If its just for the floor pan, and misc little projects, where you are ok with the use of a primer to make it look good, go for the 90 amp. 180 may be cleaner. Hell, I'm comfortable with mine up to 1/4" steel, maybe more. Save the big dog for another day.

Although frowned upon by the purists, a bonus to it's adjustability is to rig up an extension cord with a in line common 600w dimmer switch set just lower than full throttle. it helps turn down the heat for lighter gauge flux core tends to run hot. I and several other people have been doing it for months-years on end, no problems blowing it up, they are solidly built.

Look at some of the welds I've done on my body in my build thread below, see if you like them, all done with the 90 amp with aforementioned mods.

Take it or leave it, do yourself a favor and get a auto dimming helmet though.
