This is the one I have:

I love it!!! The only issue is you have to have 220 to run it. That will be an issue in looking for a welder, what type of power supply do you have or plan to have? Eastwood has some good welders but there are better ones out there though mostly matter of opinion. As I said, the one above is easy to use and it comes with pretty much everything you need including 2 spools of wire. It comes with a spool gun for aluminum too. You just have to get a gas bottle from a welding supply shop like Airgas (down here). It also doesn't come with gloves or a decent helmet. It has a stupid hand held mask which went right in the garbage when I got it.
I would find out what you are going to have for power supply, then research who has the best deal and who gives you the best bang for your buck. Miller, lincoln, Thermal Arc, Eastwood just to name a few.
Good Luck!
