For sale I have an Orange P7 frame, with a Truvativ Firex Chainset, pictures can be seen here (sorry they are not great quality).
The P7 frame, as you can hopefully see from the pictures, in my opinion is in good condition. There are a couple of nicks and blemishes (as you would expect from a used frame) but overall I think it looks great.
I've taken it into a couple of local shops, they both thought it wouldn't be unreasonable to ask for around £300 (inc the Chainset, which I'm not taking out) considering the great reputation of the frame, the condition and cost of a new P7 frame online at £450. So, I'm asking for £300.
The chainset has seen better days but I believe it will be perfectly OK for use through the winter, at least.
If you would like to meet to view the frame and discuss further please feel free to give me a shout, I live approx 10mins from J4a on the M3 in Hampshire, I dont really want to post the frame.
