Hi Frankensigns, i got mine a few days ago, so far so good. Don't expect the speed a 160k machine would give you but remember than that is because you pay 100k less...
But overall; printquality is stunning and you get the benefits of printing textures and gloss finish or matte finish on your prints this way you can easily add complex signs wich you couldnt make before.
Loafing material and switching is easy, menustructure is exactly the same as you're used too with your ecosol machine.
Today i had a problem with the white overprint not matching the cmyk print underneath but it only was half a mil, only in this case i was printing machine faceplates and they were only 50mm x 16mm... But i think i can correct that with bidir adjust.
Also printed larg panels of dibond, 2500mm x 1200mm. That went perfect.
Downide is that you always can't print edge to edge.
So if you're looking for a 'bridge' between no uv-printer and a vutek or durst i would certainly recommend the lej640.
