I know the feeling although i count it once the cash has changed hands.
Bought a Sorcerer that i watched a member here restore in a thread 5 or 6 months ago, It sat in a warehouse in LA since, waiting for a container to Australia to fill up for a Pinball importer, it's on the boat now and should hit the shore next week. I'll see it in a couple weeks after that.
That's the longest suspense i have had so far.
Bought a Street Fighter 2 from right across the country this morning, it will be a few weeks before i see that one too.
