A TB would be on my short list if I wanted to spend 2x and was headed out to be in the business as a career welder. On the farm it won't make a difference. I have ran a couple Champs, they work well, same as a Bobcat. If I was doing this in this senerio I would also consider a genset and a Maxstar type machine.
This could be done for 1/2 the cost maybe,,, a bonus is you have an electric machine too. When a guy needs gas he does but it's a super pain as an only welder if he has any kind of shop. A second shop unit could be added though, wire feed which is ideal due to the fact so much of the world is getting thinner and lighter. I actually do about 95% of it with a 180 class feeder.
I am a career welder and have other machines, about 10 of them but what I use,,,,, is a small feeder and a DC buzzer a little.
