As one of the fanatics referred to earlier GW make the most accurate A2s on the market. You can pick a decent example up on Ebay thereby avoiding the two year wait.
I agree with Andrew; check the 'Bay or sometimes even here on TFL Classifieds and you might get lucky and find yourself a GW.
Just a note: Some people dont want a second hand jacket so the two month or two year wait is better than someone else's smelly armpits lingering.
