Ok, so comparing apples and oranges then?...

They are all the same range of products to the customer.
Much as I expected, which would mean very long print times to get a good
quality product.

Quite. However, these printers aren't supposed to be making 'product',
they are there to make prototypes and but *can* be used for the final
solution, if you aren't bothered about a mirror finish (on all faces)
and don't require things to be produced at mass production rates.

Another option I might consider is using the printer to
make a master for lost wax investment casting of the items.

Wouldn't you still have the same detailing issue though?..

One of the Ultimaker videos shows a Oscar statuette they have printed.
The finish is good, but it took them 20 hours to print. Not a problem
for a one off master, but not desirable if somebody wants to buy several
of them.
