['LIVEWIRE?']

I must issue an apology to Cricklewood Electronics- having checked their website again, I find that they DO NOT list the AF 139 as a substitute for the AF127. They sell the 139 for £1.15 each, inc VAT, whilst their price for AF127 is £5.75 inc VAT. Given this large difference in price I may have decided to go for the 139 without considering that it is a UHF device. Cricklewood are now listing AF117s, but I wonder if these would be reliable in the long term
