If you are like me, you don't like or have a lot of time to mess around with lights (color, intensity, and positioning)plus the fact that each time you tweak something you have to do render after render to get what you want. I have tried creating a "scene" where the lights and shaders, etc. are saved and each new model is imported into the scene. This works somewhat but because surfaces are not all the same, the reflection will be bad so repositioning, tweaking, etc. come about. Although I like the final product from the built in renderer in Studio Tools, I don't always have the time. You might try Hypershot from Bunkspeed. There is a free trial available and what I like most is no messing with lights. The render sometimes is a little darker than I like but I lighten it just a little in PhotoShop and it looks good.
