My .02 cents, for what it's worth.
My latest Valentine 1 (of which I proudly own four), was manufactured in 2007, certainly not '92.
While the original design may have been conceived in the early nineties, the Valentine 1 has gone through some very significant evolution as manifested in its latest v3.864 and will continue to evolve, as it always has.
Using similar logic, the Porsche 911 is a "vintage" road car, however, as manifested in its latest incarnation (GT3), it is a world-class leader.
In my opinion, the Valentine 1 remains a class-leading radar detector. Is it a coincidence that many reviews (including my own) "compare" other radar detectors to the V1. I think, not. There's a good reason for doing so.
As a "true-believer" myself, the V1, remains as one of the purest radar detectors ever produced. The equivalent of a manual or stick operated high-performance sports car (like the 911), which admittedly, can sometimes be "demanding" of the driver around town.
That's why high-performance automatics are available. I would certainly put the Passport 9500i in the latter category.
But at the same time, I would take anything away from the V1 while doing so, especially on the open-highway where its reception to all radar and laser is greatly appreciated.
Ultimately, that's why I own many different radar deteectors, each has their own particular "strengths" and "weaknesses" (which I prefer to characterize as personality) and placing value on each of these abilities is a very personal and subjective thing.
In the final analysis, I am happy that each of us drivers have so many choices to make and I thank each of the manufacturers for this: Beltronics, Cobra, Escort, Valentine, and Whister.
The world is a better place with all of them.
We don't have to agree on which "features" or "capabilities are the most important, to be sure, but I hope we can, at least, be agreeably disagreeable when we don't see certain things the same way.
