I am honestly not sure if my example is a good one- I used it heavily for 6 months, no problems- really, really good machine, it was 700 in 2015 when I bought it, then about 200 in stuff I had to buy to get the Tig part to work. So lets say 900, shipping included to Hawaii. Then, it sat for nearly two years in my garage without being used- in Hawaii humidity, which is known to kill stuff. So I could be what I call "sit-itus" that killed it, which will kill nearly anything with a motherboard here. That being said- my millermatic MIG 135 110v machine I bought in 2006 is still going strong, despite sitting for prolonged periods of time.
