UK seller for the Innovate.

I cant comment on the other brands. But I bought one of the MTX from Richard above, and the quality is excellent. All wiring and connectors throughout are top notch. A far cry from their troublesome LC-1
Easy to wire up and looks tidy when installed. Comes with a white and black face for the dial so you can change to suit, and LCD display is orange.

If the PLX one does have the multifunction gauge as standard, then that would be quite good. Although you need to buy expensive controllers for each display you wish to add
