My brother used that company Peter and the service and engraving was good so no complaints. You get what you're paying for though, it's aluminium with a thin colour coating.
His was for a local kids rugby trophy and suited the purpose.
With mine, I actually cut my own out of 2mm brass sheet, filed and polished it. It was for a very personal project though and had I felt confident engraving as well I would have done so.
