Hi Edward ,
I actually use Visualize for these , I have a simple photo stduio set that I modeled and I use lights to get the look I need , I find this allows the model to match the background a bit better.
if you dont have Visualize professional , you could achieve similar results using simple shapes and emissive appearances as well.
HERE is a link to the default studio setup I put together, hopefully it helps
EDIT : I mocked up a render to show you what I mean , I did this using the Studio project I attached.
it is just a quick render but I think it gets the point across (even added the water effect )
This is a model I got from GrabCAD , I did not model it and it can be found here
