We have been using the Binatone 950s for a while now and have 3 of these. I would have been happy sticking to the 950s, but they are discontinued and have been superseded by the 1000s, which we have just bought 4 of.
The cheaper ones just don't really cut it when driving in a hilly area. Sometimes the 950/1000s struggle, but on the main they are good.
I don't think you will get a better PMR working within the legal frequencies and power.
