This is a really great deal!
We're running one of these exact machines, thanks in part to John's recommendations and content from years ago.
Thanks John!
If I were not on the exact opposite side of the country, I'd take you up on this in a heartbeat.
For whatever it's worth, the main guy selling the SMT-550's at YXING (Jim) pulled some shady moves in the run up to our purchase and left me with a bad taste.
On the other hand, the main guy at HWGC (the actual manufacturer of these machines) named Mr. Liu has provided years long and excellent support for the machine.
If you're considering buying new, buy it from Mr. Liu at HWGC, not Jim at YXING.
Good luck to whomever wins the prize!
