I know acouple people out there have printers from these guys.
I noticed reciently either thier staff or someone added a couple useful parts to thingyverse.
1. Auto leveling bed servo mount and arm for that huge print head ( printed and tried it. works great! )
2, LCD controller mount.. (Printed it , had to use a rotory tool to make the stands a mm or two wider to fit the I3xl's frame but after that works great! )
3. 60mm Fan mount for I3XL , i havent printed or tried this one yet. but its on my short list.
