The spanking brand new twin turbine I fly which has Proline 21 G2+ also has an ADF with the needles on the screen, and I used it to hand-fly a for-real NDB approach a few weeks back. Yep, it is old tech but it still provides one of the best SA aids in the game; the needle always points to the aid. Very handy when all the gee-whizery falls on its computer-driven @rse. Plus, its a good practice of the basic manual skills of instrument flying - scan, mental mathematics, multitasking... all those things that get rusty from over-dependence on the magenta line. I personally consider that issue to be way more 'dangerous' than flying an occasional non-precision radio aid approach. I get a buzz from accurately handflying an NDB, VOR or ILS. Get your kicks where you can!
