Thank you so much for the help Leeneia, I really appreciate you taking the time to explain (instead of a one liner )

I thoroughly agree with you last sentence, unfortunately, as it is my son's money and he hasn't any, this is the driver. I have located an erica in G/C which is in his price range (as in not a huge amount of subsidy from me!)and will inspect tomorrow.

As I play accordion, I will be not entirely blind.

Again thanks

Alex
