Welder advice - where to start

Thanks for all the great advice weighing in all around.

I'm leaning toward this Harbor Freight multi-process welder. This will give me the potential to get into easier MIG stuff right away but try out TIG - also there's a bunch of digital controls that allow presets which I'd think would help make it easy to set it up for a given application. Granted, it's a cheap Harbor freight brand, but I don't expect to do high-volume work with it. The reviews seem OK.
