Most of my results from the HiTechnic sensor were the opposite of this.
I find it to be very useful, so I use it all the time. The readings seem to
show a good, linear output based on the distance. (even though I usually use it
as a binary detector)
The ranges are close to the same. Min 6" (at that point, the reading is pegged,
and remains that way as an object gets closer than 6") to max ~4'.
This is a pretty large sensor, and at $80, it's not cheap. But, I think it's
worth it.
