Check out this company. They manufacture some nice looking engine monitors. If your building an airplane and haven't yet decided on instruments, maybe you'd consider these guys. www.advanced-control-systems.com
I have flown quite a bit in Lancair's and I've always been disappointed with the engine monitoring displays. They're usually digital, but difficult to interpret or they require you to shuffle through many screens to find the info you want. This looks like what I would choose to put in my Lancair. All I ever need to know is displayed on one screen, not requiring me to shuffle through different screens to see what's happening up front. http://www.advanced-control-systems.com/Installations/KarichPanel.jpg
