well there is certainly mixed feelings on this issue lol, I for one love new tech and would want to be there using it, however it is a personal choice and those that want to use the ear drum can, no one would force them to upgrade, my hearing is slowly getting worse so a visual aid too would definantly be of interest to me.
The avoidance of tax would be the farmers problem for not disclosing it, I ran a rally a few weeks back and the farmer is going to be paid, its all above board in our club accounts stating the farmers details and a cheque made payable to him, its not our clubs responsibility to ensure he reports the unearned income to the revenue that's down to him.
Happy hunting every one which ever way you chose to go.
