Don't have direct experience but after some research this is what we are about to install in our plane.

We are putting one of these on our Silent Auction for Oceano Airport Celebration Day, May 12,  and I am going to bid on it too!      I like that it has altitude alarm settings.  Very cool!

It was generously donated by Electronics International.

I've installed several of those and the next one will be in mine. Very cool unit !

Installed an EI SC-5 in the plane last annual.  Really like having local/zulu and the timers.  I didn't expect to use the engine timer much, but have found it is great for keeping track of hours since oil change.  The lighting of the instrument is also quite good.  I would install it again.

That EI looks like a good unit. Cheaper than the chronometer on my wrist, and does more than just tell time.

But my vintage panel is quite full, I would have to remove something to make space. May have to redo the panel when/if ADSB ever gets going . . .

I installed the Davtron M803 in my plane when I redid the panel.  I like having the digital OAT display, and didn't really want to deal with wiring it to the encoder like the EI wants.

We are installing a Dayton M803. It has 4 time zones, timer, volts, OAT, and it's backlit.  Downside? 400$.

Byron, if you keep an eye on eBay you may be able to do better--I got a NOS one from Cirrus for about $200.  It was a 28V model, but that only affects the backlighting (and the bulbs can be changed if you're handy with a soldering iron).

I recently installed in my airplane the Davtron M802. It's brand new and not out quite yet but I'm testing it for them. I can tell you it is an excellent chronometer with countdown time, elapsed time illuminated buttons and all the features Davtron is known for. I like it especially because it displays both GMT and local times simultaneously in a nice graphic dimable display. It is an excellent dedicated chronometer. I'd recommend it highly if you are not in a particular hurry.

I also have the Davtron M655 multifunction instrument (volts, PA, DA and OAT) I love to have DA at the push of a button. I like it alot and I really like Davtron as a company. Very customer friendly and responsive.

I have a Davtron M811 clock and M655 OAT/multi-function instrument and like both of them very much.  Don't be afraid to check eBay for these units...they come up frequently and are simple and robust.  The factory can support them if needed for modest cost too.

I put an EI in 2years ago. Love it.

Yes we are replacing it with the Davtron. We keep the OAT plus gain a clock and voltmeter.
