I started with a lincoln 120v mig, used for $200, wish I didn't sell it.
It was very easy to use.
Moved on and bought a chinese AC/DC stick/tig/plasma cutter.
I reach for the stick most of the time, its a joy when you just need a quick fixit job.
Today I would buy a 240/120 switchable machine, I like multi function, everlast is good value.
I don't have 240 in my garage so I use a heavy rubber 240v extension I bought from an electrician.($50).
It works perfectly fine but I don't use it when the grass is wet or raining.
Its worth it to have 240v, I would NOT buy a 120v machine again.
You can dial amps down but can't go above what isn't available.
