There aren't many models in their Linea Maestro line really, most of them are in the pictures starting this thread. Personally, I loved the 3-eyelet wholecuts.
I believe that model is from the "regular" Linea Maestro, which is €250+€35 for the trees = €285. Shipping via mail should be somewhere around €35, but could be a little higher depending on package weight. Package insurance, etc. also could add some to shipping costs.
So that would make €320 = $417 + possible extra shipping costs...
So 11.5UK is it? Beware, if your feet are a "regular" width but you usually need a 12.5 because of length, you might have to size down a little less! Do you have enough toe space in your 12.5's?
This "New Rey" last is pretty elongated though, so that might not be a problem and 11.5 would work fine...
