Im looking at getting some prosport gauges but there offering them in either mechanical or electrical format, what is best. (does this mean the way the needle moves or how the data is recieved) :freak3:
cheers

It's both. Electrical gauges have a sender which takes the data from wherever, converts it into an electric current and sends it to the gauge which reads it, converts it into movement, and displays the info.

Mechanical gauges have a tube or similar which attaches to the gauge and the gauge reads the pressure etc off the tube.

Personally, I'd go for electrical. Here's why:

No tubes with hot oil/vacuum to leak inside the car.
Wires are easier to thread and route than the semi stiff tubes that come with mechanical.
Wires are easier to route around the engine bay, and don't suffer if kinked.
