Any Good all-in-one Speedo,tach, warning light guages?

[Bssoap74]

I have a 1979 and want to replace my guages with a single all-in one and keep the warning lights. I want something semi-small since I will bob this bike at some point. I also would like to not spend a ton of money. Are our guages mechanical or electrical? I believe they are mechanical, just want to be sure. My speedo jumps all over and shakes while accelerating.

you can get electrical gauges but they are £$'s

a good compromise would be mechanical speedo and electric tacho.
