I went there on my last trip to the UK, and had a chance to talk to a 92 year-old gentleman who had helped build some of the machines during the war, and had been involved the project to reconstruct the Colossus machine. There isn't the huge throng of visitors and high security like at other museums. I was able to walk behind the cordon and get a up-close view of a running Colossus machine. It feels like a place with living history, and I highly recommend visiting! Edit: There is no shortage of Enigma machines in museums, by the way. I know there are ones at the NSA museum, the Imperial War Museum in London, and Bletchley Park has several. If someone wants their own for home use and they can afford it, I am all in favour of that.
