You're in the right place for exactly what you're trying to do. I will let others explain exactly why that doesn't sound lame, but rest assured, you aren't so different than most anyone else here!
I see you already have a want list up - that's a great start. Do you have the cards available for trade up too? If you add those to your "For Sale/Trade" list, the system will automatically match you with members who have your wants and cards that you need as well.
You might be surprised at how many people are still trying to fill their needs from that era - myself among them. Unfortunately, I'm still working through a multi-year re-organization, so I'm not looking to bring in much right now. That said, I also notice that you have a couple of needs that I can help with. Send me your address via PM and I'll mail them today or tomorrow.

I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
