I have used one of these. Its what you pay for really. If you want a all singing all dancing radio set, buy a spektrum, i bought an DX3s off her for a £100 with all tele and 2rx's. Je spares have an offer on DX3 £114.99 its a bit more then the acoms but i think your mainly paying for quality. Even better idea buy a second hand one. Seen a spektrum dx3 floating around in the for sale section for £70
Tell us what you buy mate.
