I have a Cubex duo which I bought in September 2013. The printer is like new, I actually only used it 5 times. All is in perfect state, including the original packaging and a few new ABS and PLA cartridges.
If you are interested please drop me a line at email@example.com.
Can you advise how much you paid for the unit in 2013
What size bed it has
How much are you wanting for it
