Thanks Maggy
The reasons that you list for keeping them are much the same as ours, with the added bonus that my wife loves the look of them too!
I have found a (very) local breeder using the hillradnor website who is only around 4 miles away from us, so I will get in contact with them and see where we go. There was a sale in Talybont on 8th Sept, which we missed, but I am sure there will be others.....
Useful list of breeders on the website too!
