Looks like a nice machine for the money. I can't tell for sure, but is the frame/body made from metal or MDF? The answer to that would change a lot of things...

[Xnaron]

I am pretty sure it is made of steel. I suspect it is made in China. There aren't very many specs listed for it though. It might be a good base though to start with. Better components could be added later or could they?

300 oz steppers are pretty small for a machine of that size, and I suspect the drives aren't as good as Geckos, but that's just a guess.

[Xnaron]

I could install better steppers and gecko drives. As long as the rest of the table is good. Anyone see any obvious design flaws?

thoughts?

It says it includes Mach software and connects via USB. Mach2 or 3 don't work with USB, though. Parallel port only. 0 feedback would make me a little nervous too.

Brendin,

Unless you want to be a guinea pig, insist on references from the company. You need to talk to customers who are using this machine. Get their feedback before you purchase.

It will be well over $5000 delivered. Nearest port? Like Wilmington or Oakland, or nearest truck freight terminal.
Not bad but, there are no closeups, and no pictures from the back; the "Sunny USA" address makes me nervous too.
Also from the way the light reflects in one of the images it appears that the white metal may be quite thin.
What diameter are the ballscrews, one has to be around 9 ft long. How is the gantry stiffened? What type of bearings are used on the rails? Is there a power supply for the steppers?
There are missing and inconsistent details that could make this a good or bad deal.
Ask a bunch of questions; the way the answers are handled will tell you a lot.

I don't know what to say.....
Here is another one

Starting bid: $4,299.00
Its hard to believe that somebody sells this kind of toy for the price of the spindle (1.5 HP 1000 to 24000 RPM, Water Cooled)

Not one photo shows details of the machine. Would it cost them to open the doors and get some close up shots?

There are simple "do not buy" filters for this kind of business.
Shipping insurance and credit cards.
Legit businesses offer and use both.
