Anyone have this machine, or know anything about it?

Anyone have this machine, or know anything about it? It has a lot of nice specs and features. I imagine it is of similar quality. I am considering some different projects/endeavors and the larger size will be needed. The additional features are just bonuses. Currently selling for $1899, I would see if I could get a better price if I pick it up in person.

I was also considering this one on eBay. A little bit shorter in the y axis, but I think it would still serve my needs.

The one in the Craigslist ad is an old model

Good to know, thanks. I was leaning towards the eBay one. Better price, same features.

@Brandon_Smith I think Scott Thorne has a 50W model. Not sure if it’s the same as this though.

3 sizes on the same ebay link for comparison
become a very big machine (box) very quickly.
