Well I got my Pro 73 today and I have to say one thing: Outstanding!
Although the different tones for X, K and Ka could of used a little better sounding, over all the Pro 73 worked excellent!
I took it to town and picked up 4 LEOs and 2 K band doors which I've always picked up. Over all the range was pretty good and if I had to recommend anyone an RD in the $150 range I would definitely recommend the Pro 73.
Like with stealthcb the Buttons took a little getting use to but once I got use them I had no troble at all. 8)
