How Much Have You Lost Thru' The Upgrade Process?

I think the answer to this particular question is too embarassing $$$ for some of us.

I don't think I've lost anything. I've traded some $$$ for items that I wanted. So far, I'm happy with the upgrades I've made. Like you, i don't upgrade as much as some do. But the ones I make are usually researched very good before getting them. My most recent upgrade was the signature arm for my ScoutMaster TT. Worth the $$$ to me

I look at the loss as the amount I spend on my hobby, in which case it's not a "loss" at all. I tell myself, what if I were into boats or golf or some other pricey hobby.

Not one red cent.
