Currently, I'm using an X50, and I love it. It has never failed me.
I live in Fort Worth, TX and the school buses here have K drones. Very very annoying. I have my X50 in exp. mode so when it picks up 2 K signals, I know it's a school bus. I've read that the Valentine can display up to 8 different signals of the same band, correct? That would be very helpful for my situation, since I'm bound to screw myself over with the X50. Why? My X50 shows only up to a max of 2 K signals, so what if I interrpret those as a school bus when it's a school and a LEO parked on the side of the highway? :/
So far, I've only witnessed Ka being used by the Fort Worth cops, but I've read they use K for sure. The only thing I'm really scared of is laser.
I also have another question about the Valentine. Does it have an exp. mode like the X50? Also, is that 8 bogey counter a total? Or is it 8 for every band? As in, like 8 Ka signals, 8 K, 8 X.
I will hate to part from my X50, but if have to, I'll do it.
