Looking for some panel advice. I am about to start IFR training, not planning on much IFR but want the option. I know the FAA just changed the ruling for the 3 approaches you don’t need 3 different instruments anymore so I could do it in my plane with the existing kx125, kx155, and ki209.    Initially I thought gps175 but then panel redo will eat into the cost due to moving things around. Instead I could do GNX 375 get rid of the ESG. Or GNC 355 and get rid of kx125.  Thanks!
