Jose L Piedra for me, can be found around Europe for about £1 each, excellent value for money.
Can he get hold of them ? If he could and sold them at a reasonable price I'd become a customer.
It's worth trying the search facility as there are two places that have been used and recommended in the South, I believe one is in Chessington and the other in Kent. From memory they were around £700-£800 inc VAT.
Let me know if you can't find the information.

You can get a replacement for ~£700 fitted. Also, there is a company in Swansea, I believe, that can replace and re-use the glass and costs £200-300. The search facility will help you find the details in previous posts.
