looking to buy my first welder

hey guys
im looking to buy my first welder

here is the thing, i know how to weld but i never owned one before
i think there is a welder plug in the downstairs garage, but honestly, all the places where i expect to be welding only have 110

at this moment there are 3 or 4 little projects around the house that need welding but nothing big, so im just looking for something affordable

while were on the topic, how do you guys feel about flux core welding?
does it make sense to go with fluxcore and not need tanks or does the wire cost more then the gas and tanks would?

im hoping to keep this under 500 dollars, and im not opposed to harbor freight

so, what can you guys suggest?
I have this welder. It is not the best welder on the planet, and it has the click selection for amperage.
Lincoln Electric Weld Pak 140 HD Wire-Feed Welder K2514-1

I have abused the hell out of this welder, totally disrespected the duty cycle.

It keeps on chugging like a trooper. I can do a pretty nice job using 75/25 shielding gas. My buddy, who is a Journeyman welder has turned out some absolutely beautiful welds using my Lincoln "piece of crap"
Was worth my money several times over.
