Has anybody ever heard of this printer!

Has anybody ever heard of the Focus l8 single extruder and does anybody have any links or more information as to how good this printer is and what it can do? your replys would be most welcome

Or has anybody ever heard of a Wanhao d5s large build? I am thinking of buyig this printer to see how good it actually is, does anybody have any better suggestions? your thoughts would be good right about now.

What advantages do you see these as having over your current 3D printer?

Are the advantages something that you can not get from some simple modification of your current self built 3D printer?

I have not got a 3d printer I wish to buy this one as it does large prints, the Wanhao d5s? is it a good buy?
