I’ve found a great supplier for strings and the like, Soundpost, it was reccommend to me by Duncan Riddell (leader, BSO) and has proved time and time again to be ever so reliable.
Brian Cohen seems very reliable and always reccomends decent items for the price bracket I am after. Everything arrives very quickly and is fairly cheap.
