I still haven't got it 100% clear because it became cloudy outside, but it's a big improvement. I haven't managed to get a Vader yet, but he's definitely one of the more expensive ones. I'd say £200 at least and you're probably better off looking on Ebay USA. All mine bar two have come from America so far, there just aren't many for sale in the UK.
