I would (and did) opt to get the wire welder that offers gas/no gas option.
Bottles are pricey but sooo nice to work with. You may want to use the gas later on, it is nice because the welds are much cleaner with less splatter to clean up.Nicer looking welds too.I bought a Clarke 130EN . It has been pretty good.
Them old stick welders work OK if your builing a corral out of pipe or a cattle gaurd or something and they are cool to look at, but as mentioned if you like working on them as much as working with them...welll then....
I bought a cheap generator as a backup fo my heating system ( an oil fired boiler with 2 zone pumps), makes about 15 amps continuous. I paid like 200 bucks delivered to my door, granted it is a china made job, but it only has to work one time to be worth it.If the power goes out where I am at, at least I wont freeze to death, as far as an Icebox, I just step outside...LOL
