OK guys... point taken... no need to rub it in!
Not quite sure why my MM post has been moved to the "Audio & Visual" section though, but at least it does still appear to be vissible in both.
I am now seriously considering a price reduction, as I accept that is not really fair, of me to pass the effect of my mistake onto others, and I would like to be seen to be doing the right thing, as it were.
Hopefully the Guide is worth something to someone... but obviously not anywhere near as much as I paid for it!
If you do price drop, remember to leave it 24hrs!
