FWIW IMHO the gauges were largely a waste of money
I kinda know where you're coming from there

(especially with that bottom 'guage' - watch stopped working VIX??

). I also take your point about that not being the best location - having dummied it up in my car with a convenient piece of cardboard my left arm is going to pretty comprehensively block the guages except when changing gear.
Having said that, I'm still going to stick two guages in there

. I'll pop in a boost guage - mainly for diagnostic use anyway. It's not one I think I'll look at all the time - only if I think there's an issue (in which case I'll be waiting till I find a nice straight to remove one hand and take a look anyway). Second guage will be a combined oil pressure & temp which tbh is the one I really want. After much debate I'll be going for a spa-design digital unit - I know you can't read the actual digits very well when driving - but they do come with user customisable warning lights. My thinking being that I can set the warning lights to quite conservative levels - they're bright enough that I'll spot them out of the corner of my eye anyway - and if I see a light come on I know it's time to come in (or pull over sharpish!).
All pie in the sky at the moment though - feeling pretty skint right now and if it's a choice between 2 guages and a couple of trakcdays (which it is!) I know which will win
