I just had my TK45 standard bellows replaced by (what used to be Camera Bellows, but what is now) Custom Bellows in the UK.
I cannot believe the quality, speed and price of the replacement. They are just fantastic. As you can tell, i'm a very pleased customer.
Communication with Keith was superb and the replacements were ready before I though they would have arrived from Norway!
Drop Keith a line at: email@example.com or point your Interweb browser at: http://www.custombellows.co.uk/index.html
BTW, I have no association or affiliation with CB, other then that of a satisfied customer.
