I spent ages waiting for a Gemini X to appear for sale, got bored of waiting in the end and got hold of a 40MHz Gemini II with RX for less then a couple of pints. I tried it racing in 40MHz setup to see if I got on with it and I love it, so ordered the 2.4GHz hack module and RX to convert it. That came to about £40 all in.
It has all the features I will ever need, including subtrim which seems to be missing on a lot of cheaper sets.
Typical there's 2 X's for sale now!
