Welding Tips and Tricks

I'm looking at 2 plasma cutters.
Both are new in the box but around 3 years old.
One is a miller spectrum 375 (I believe transformer) for $600.
The other is a ESAB PCM 875 for $800.
I am just small time hobby welder. I have good 220 power in my pole barn so the MVP isn't all that important.

Ive used a similar model to the spectrum 375 and it runs quite well and for 200 dollars less I would most likely go with the miller.
