Last year I had found a cheap Chinese plasma cutter on Amazon, it was a Lotos LTPDC2000D plasma cutter, it never worked so I sent it back to Amazon, then I found a good deal on a Thermal Dynamics Cutmaster 52 plasma cutter that was not much more cost than the Lotos.
Here is a product page for the Lotos LTPDC2000D, I think Lotos went out of business:

and the product page for the Thermal Dynamics Cutmaster 52 plasma cutter that I have now:

BTW if you want to see the guts of the non-working Lotos LTPDC2000D, have a look over here:
