I'm selling my Faber twin 7's with old style MDE manifold, due to lack of use. I've owned them from new in early 2009, they had their 1st visual test in January 2010 and so are in test until July 2012. These have been in the water less than 10 times so are in fantastic condition. The O2 clean has lapsed and they are currently full of 32% Nitrox. £275 PM if interested.
