Miller180 vs. Lincon 180

So I am in the market for a new welder, my choices are the Miller 180 vs. the Lincon 180. Lowes has the cheapest price on the Lincon at about $650. My local welding supply shop has the Miller for around $800. The miller is sturdier built, i.e., cast iron roller parts nad wire tension pieces vs. plastic on the red one. I have been reading reviews on the both, and it seems to be an argument over preference, like chebby to MoPar. Reviews say one has a better arc over the other, and then it turns to an argument over which one is better. For the average home hobbyist, I would feel just fine with the Lincon, but I hear customer support is better on the Miller.
Does anybody here have either one? Or have any input on either one? Any help is much appreciated.
