For months now I have been tooling around with a refurbed 8500/X50 (S7) and it's been doing a FANTASTIC job all around. The detection range on Ka (34.7) and K-Band has been so good that I don't feel outclassed without an M3 on the windshield. Even had a nice save on X-band in NJ cruising +20 over the PSL.
I have been waiting for the new announcements coming before summer to decide on what to get next......but now there is another version of the old S7 resurfacing that I just had to grab for the price. I'm hoping the USA mode and S7 combo on the refurbed unit will kick it up to the next level on Ka......although the X50 has been blowing my mind, I suspect the RX65 might be even better.
We'll see in a few days.
