For anyone thinking about getting a VR3 and want to have a look at what it looks like on a dive, they've put a really nice simulator applet on the website:

You can play with some of the options too...
The unit you can play with there is a fully specced up unit, capable of Trimix OC and CCR. It's even got the BIG graphics mode and the blender.
