About a year back I bought a Hobart 187 from Northern Tool. They had the best online price and were running free shipping. Between the welder and a trip to my local welding shop for a gas bottle, auto-darkening helmet, large spool of wire, and gloves I was pretty close to $1000. The steel for a welding cart probably put me over that figure, but it was less than a factory made cart, and a good first project. Had a few bucks into the wiring and such for a 220v outlet in my shop as well.
In all, I'm happy with the machine, and the deal I got. If I had to do it again, the only thing I would have done different would be buy the welder itself locally. Not bashing NT in any way, but the local welding shop would have made me a package deal, and the final cost would have been the same or a couple bucks less. They are also the regional Miller/Hobart service center so I'll be dealing with them if I ever need parts or service. Aside from supporting a local independent business, some consideration should be given to service after the sale when choosing brands. If you buy from Home Depot/Lowes/NT/tractor Supply etc... and have a problem, they'll just refer you to whichever welding supply house is the local service center. Why not just start at the welding shop? Besides, there is a pretty good chance the sales rep at the welding shop knows more about his products and which one would suit your needs and budget better than the tool corral attendant at the home center.
