Hi, I think the Z axis travel is 65mm on that model which might be a bit tight if you wanted to put a spoil board on the bed as well. Even without a spoil board using 50mm stock would only give you 15mm for the cutter and depth of cut, machine travel etc. Also I don't think they are VAT registered, so if it is a VAT registered company purchase that might be a factor. The guy that owns premiersign is registered on here but I can't remember his name.
I have the Eagle IV model.
