I've been using an Extron ADA 3-80 RGB video DA for distributing standard 
frequencies to other instruments.  It has worked very well for me.  They are 
frequently available on Ebay quite cheaply.
.There's a good discussion on using the Extron DA for 10MHz frequency 
distribution at http://www.ko4bb.com/ham_radio/Extron_3_80/. There's a 
couple on Ebay right now (Item 160867891412 and Item 370641502891 {different 
model}).  They're in the USA, so shipping to the UK might be a bit painful 
unless you can get someone to act as a shipping agent.
Other Extron models will probably do as well... chech out the Extron 
literature for details.  I like the ADA 3-80 because of the number of inputs 
and outputs it offers.  Bandwidth is great and noise is low.  If you need 
really low noise distribution, you will have to determine suitability for 
your needs.
