You should be posting these sort of threads over in the Junkyard.
As you're a new member, there's a big 'want to buy' thread to post in: http://www.therpf.com/f13/new-member-want-buy-thread-112776/ Once you've been about for a while (I cant remember what the minimum post limit before you become a full member, something like 20 or 30) you can start your own WTB threads.
