Hi Madscouser,
We're also uk based, so understand your concern about the fx rate, but unless it drops sharply it wont make much difference, perhaps less than £100 overall.
I can't find the listing you mention, so don't know the price pp.
You wouldn't pay any annual dues, if ll the 2014 points have gone. I would be inclined to ask the seller to contribute towards closing costs, rather than offering less pp, that way there is a greater chance of passing ROFR.
There is a thread on this site which tells you what price pp people are currently paying, it might be worth a look as a guide.
Happy looking
Just adding s contract offered through fidelity? I didnt check them. I asked on a uk based forum about them before we bought our 2nd contract and the reports weren't favourable. Maybe have a look on the site I'm talking about. Its called the dibb.
