Yup. Me too. I just can't deal with incomplete TFs (figuratively and literally).
If I get something incomplete, its going ot bug me. And I just don't have the time to hunt for parts. So that's just going to bug me more.
Solution is that I only get complete TFs or not at all. Most of the time, I'm happy to pay a slight premium to get TFs complete (definition of complete = complete, nice stickers, w/ box or card).
Exception to that would be duplicate pieces of TFs, which need not be complete.
