Might be starting this in the near future. Took me a while to get hold of one at a good price, but a few months ago I finally got one.
I also have the extra parts set that includes the parts for tanker and photo reconnaissance Valiants, but I'm not sure if I'm going to use it yet.
I haven't decided which scheme she'll be painted in either yet. I know I don't want to do the photo reconnaissance scheme (silver and red) and I'm not keen on the all silver second prototype. So basically it's between the tanker in anti-flash white, two bomber schemes in anti-flash white, and the camo scheme depicting a bomber shortly before the Valiants were grounded.
I'll also be looking to pick up a micro mir 1/144 one at some point as 1/144 will be round 2 of my v bomber project (the Victor will be micro Mir's new Victor b1, and I'm hoping they will do a vulcan b1 soon).
If anyone's got any Valiants they've built, please post pictures (or a link) here
