There's others on here that know far more than i do about these but looking at the ad and which site it's from, I would say these are the Triumph Instruments PRC functional replicas of the Harris PRC-152 etc. They are functional radios but are certainly not the same thing as the RS Harris radio. I believe they have similar functions to the Baofengs but can't say for sure as I have yet to invest in either.
The actual Harris 148 or 152s would likely be in the thousands just given what I know the average LE portable radio costs.
Here's the real thing:
