I need to free up some cash (I've been spending on lenses again) so will probably have to sell a pair of bins. The three currently seeing the least use are my 8x20 Ultravids (near mint condition), my Leitz 8x40 Trinovids (well used but still great optics) or my recently acquired Nikon 9x30 roofs (I know very little about these). So what do others think, which would you part with, and which will give me the best return?
The Leitz will bring some money. I think I am the only one interested in small 9x binoculars. 
It´s not an easy choice, is it? Binoculars are not the most liquid of assets, and each one has its own charms in any case. I know a guy who might be interested in the Leica compacts, although I´d imagine you´d have no problem shifting them in the UK. Let me know if they´re the ones you want to sell.
