I am fortunate that I have an arrangement with the wife. As long as its a TF that I really want, I can get it. I like that as over the years, I would try to complete the lines, and I have long since ran out of display space for everything. This weekend I might even start putting up more shelves in my office and start working on the pile of unopened TFs!
We're in the process of renovating a new house and I'll have an office for the first time. It's going to be mostly shelves. Pretty excited about it, as up until now I just had a small set of shelves in the basement and everything else was just stored in boxes.
