I don't have anything to sell you I'm afraid. But in regards to the Granite gear crown, I posted a thread last week to see if there were any about, and someone responded to tell me that they had only been out in the UK for a week or so. You might have trouble getting a second hand one, but you can get them new in the UK from here:

Alternatively, they have it's predecessor, the Vapor Trail for a bit cheaper:

Only one left in stock.
As for the waterproof trousers, go and get yourself a cheap pair of the regatta ones from go outdoors or somewhere similar. Mine are a small I think, and they only weigh 170ish grams without the stuff sack. Not breathable though...
