The Bendix King KLR-10 was just released. Super cool, but $1,500.

An AOA properly calibrated will give you a much better safety margin as you will be able to see the AOA increasing whereas a stall warner gives you less information.

Yes, an AOA is going to be a little more expensive, but when you operate into a short strip using AOA, your confidence will be a lot higher.

I think AOA should be required equipment!
This is one of the best stand alone units IMO:

This hits the nail on the head. Regardless of difficulty, you owe it to yourself to have AOA installed. I believe once one has it, one would not want to be without. The feedback you get (well before critical angle) is invaluable. It's great to see just what the AOA situation looks like on the classic base to final turns. Maneuvers that you once thought were well within the "neutral" zone may surprise you. If anything it makes you more cognizant of being low and slow.

Being a former Naval Aviator, I'm a big believer in AoA. In fact, I have three different systems in my RV-10. The one I like the best - and the cheapest - is the Lift Reserve Indicator. It is purely analog, except for the light inside the mechanical gauge, for (ugh!) night flying.
I mounted mine where it should be - on top of the glare shield.
There are lots of brands of LRIs out there, and they are pretty much the same. I'd look for the cheapest one....

I concur. I've been flying an LRI in the RV-6 for a long time and it is simple, inexpensive, reliable, and my primary instrument for managing the pattern and landings.

As a bonus the LRI probe can also drive the AOA indicator in the Dynon to provide an audible alarm.

Welcome!

Does your new plane have a Dynon EFIS installed, by chance? Do you want one?

Dynon makes a very good AoA but you have to have one of their EFIS's and Pitot tubes.

Installing their pitot and the AoA line isn't that difficult.

This is what I was going to post.

Dynon pitot/AOA combo and a D10 will give you what you're looking for plus a battery backed up EFIS.

If you want to drop a little more coin, I have a 10" skyview with the same pitot/AOA. Works great, plus all the features of the SV system.

Garmin has jumped into the water with a pitot/AOA system on G3X too.

Others have mentioned the AFS, LRI and Bendix systems. Lots of choices out there.

Beware, so many cool toys out there your wallet will get really light really fast!!!
