I find the OEM look is the nicest, just change the lights to a more modern colour to update the cockpit. The UK spec speedo is a different OEM look but if your facelift you would need to look towards the aftermarket stuff for a MPH/KPH speedo face. TRD is nice but very expensive and extremely rare, the cheaper option is TRD "styled" gauge faces.
IMO electronic gauges are crap, you would be better off with a mechanical gauge for more accurate readouts. Granted they don't look as "flashy" but I'd take substance over style any day.
