So I recently started a thread about whether I should buy a Escort Redline. Well I just noticed as did others that Escort is again selling refurbished RX65s (S7) on eBay. I have seen tests where the RX65 (Ka USA MODE) picked up Ka Q/T shots better than a V1. Now the question is which one should I buy now? Theoretically isn't a RX65(S7) a better Q/T detector?
