CO2 LASER ENGRAVING ENGRAVER MACHINE CUTTING 50W WITH UP & DOWN PLATFORM | eBay

I was talking to G.Weike for a while, but unfortunately the shipping costs for a machine from China was kind of impractical for me, at over $1K!

I have been looking at these machines on eBay for a while, they seem to be the next step up from those horrible K40 style machines.

The pro's and cons I see:

Pros:
Decent looking laser head and optical mounts
Pretty typical tried and trusted linear bearing system
Adjustable Z axis
Inbuilt DSP
Decent sized work area
Includes a rotary axis
Ships from Brisbane

Cons:
No belt reduction (Or that I can see)
No honeycomb
Claims 50W laser, but looks like a stock standard cheap 40W tube
Ungrounded US plugs for water and air pump

I think this is probably the best I'm going to get for my budget of around $2-2.5K (Seller offers a 10% discount).

Has anyone bought or used one before? I'd love to hear experiences
