Conrad Electronics used to do a rotator for less than £60 but discontinued it in 2014 which is a shame. Don't know of any others at this sort of price.
I asked the chap at Wellbrook about matching . For radios that have a balanced input (three of my domestic sets have this facility) he can supply a Balun which might improve the sig to noise performance even more.
On radios that don't have that, just long wire input, I don't think a transformer would make much difference. You could try adding a few hundred Ohms in the lead to the aerial socket but probably you will lose as much gain in this as you do from the mismatch as it is.
