I have an Eastwood unit I picked up a few months back - I'm with New Interiors - waited way too long. I use it all the time.
If you are cutting a long straight, clamp on a piece of angle iron and let it rip. Minimal slag, and none of the noise and hassle of a cut off. Had to notch the upper control arm on my truck to clear the headers. Was going to take it off, then figured I'd just reach in with the plasma and cut it off - saved me a couple hours and an alignment.
You will find uses for it every day.
