Chinese box! Everlast, Longevity, Eastwood... Go with the best costumer service, cause you'll probably need it! Eastwood have the best support for what I saw on weldingweb.com , but you are in alberta so you might want to have a Canada support. Everlast and Longevity have dealers in Canada, not eastwood. Thoses welding machines are like flipping a coin... You can get the good one first try, or not! Check Warranty and specs. I've tried the Everlast 250ex last week. Pretty good tig for the $$$, but my friend had some troubles at first with it, need to ship it back for a new unit. I'm personnaly heading for a Thermal-Arc 186 ac/dc tig cause this brand stand behind there products and my supplier is near for support. I can't afford Blue or Red, my wife would kill me.
Everything depend on your needs and budget!
