Hi and Welcome to IKEAFans,
What a cool idea to get someone going on their IKEA obsession. I highly encourage that kind of behavior.
The most I can do is push you towards Ebay and Google. You've done your part by posting here so thousands of IKEAFans will be able to find your request.
I know you don't really care what product you want to buy, but it might be easier to search for items if you know some product names. Too bad IKEA.com doesn't have old catalogs online so you can search for items that look appealing to you.
