The work I've done has mostly been DVD related and everything has transferred over pretty well, but most were not over the top pieces of work. If they provided you with a template/specs and are accurate with their work you should be fine.
One particular project had me really worried as I hated the way it came together and I was sure it was going to be off the wall weird when on the shelf and in hand... but the end result was exactly what the guy wanted so.
