Hello Jennifer,
For around the home use and practice, the imported machines may be a good deal. If you have the money to spend, get a Miller Thunderbolt 225 AC/DC or Lincoln AC/DC 225. The DC option will increase the price but will also increase the capabilities.
With DC you have the ability to TIG (GTAW) weld should you ever get the urge.
I have 3 imported DC inverters. One from harbor freight ($149.00 ish) that is limited to 80 amps. One from "ARC ONE" that was sold as a tig machine ($250.00 ish) and one that is from an importer that I recently got thinking that it couldn't weld an 1/8" 7018 at 60% duty cycle at 140 amps (<$200.00) . All of the above machines are inverters and more efficient than transformer type machine.
With the imports, I think it is hit and miss on the quality. If they work, they work as advertised, if they don't you are at the mercy of the quality of service from the importer.
The machine I received from the importer was a good deal for me as I traded out reviewing it (still in progress) for a good deal on the machine. Though I haven't fully tested it. I would pay every bit of the retail cost for it.
There are some advantages to getting a name brand machine and if you think you are going to use it much, saving the $ is possibly a good idea.
The characteristics of an industrial machine and a "home use" type machne may vary however anything that melts a rod will help you develop hand eye coordination.
Here are welds made with the <$200.00 import machine.

I also have pices of weld made with one of the small 80 amp inverters.

Hope this helps. There may be a great deal of information forthcoming regarding global economy and the like. Its over my head.
