Be aware that the Dynon EFIS requires a laptop to configure.  For those with a laptop handy, this is no problem, but if you don't have one, it's expensive and inconvenient to rent one.  Also, the display in the Dynon EFIS is only good to 50°C.  On a hot day, I'm sure the temperature behind the Legacy panel is above that, so you run the risk of your display blanking out.  Finally, in order to use and calibrate the AOA that they offer as an option, you have to do full stalls after installation.  That wasn't something I wanted to do in my Legacy.  Slow flight, approach to stalls, fine, but fully developed stalls just to calibrate an instrument?  Nope.

   Inicidentally, the JPI EDM-900 also requires a laptop to configure.  Most, but not all of the parameters can be configured using the display and the button switches.  To get it really set up right, however, you have to have a laptop.  I like the EDM-900 very much -- the displays are well thought out and it's far superior to LCD's for readability.  I had a VM1000 in my previous plane, and much prefer the EDM-900.  JPI don't tell you in any of their literature that you need the laptop, so be warned.  Also, if you don't actually specify what you want displayed in some of the bar graphs when you order it, three of them come with no labels!  Don't assume you're going to get what you see in their ads.  They show OAT in the right-hand position of the second row, and fuel quantity, L and R, in the 2nd and 3rd positions of the third row.  If you don't specify that's what you want, those three bar graphs come blank!  Grrhh...
