dont know if i got here in time, but i would never get a flux core welder, and i really don't think i would get any sort of welder from harbor freight. see harbor freight thread.
BUT. that thing is only $150 and you can hook up a bottle of shieldpro and mig with it so maybe it's worth it since it's so cheap and you probably only need to use it a couple of times. it might be a worthy $150 experiment to tell me if i should buy it.
if you want a GREAT little mig, there's a little lincoln (the same one rooflechikken is probably talking about) that we used for all our on-site weldering and that little thing was AWESOME. it's labeled NASCAR and the machine + wire + gas and everything should run about $500. obviously far more expensive than what you posted but i will vouch that it is an excellent machine. it's rated at 5/16" steel but we welded 1" square solid stock after chamfering all the edges. this is the welder i would like to own.
also it runs on 110v so you can weld in the kitchen.

^ that one
ALSO we got badass auto-darkening face sheilds from harbor freight for like $30. i say badass because good luck finding autodarks for less than $200.
