Everyone's situation will dictate a different response. What I find is time changes all things and what is right today may not be right for tomorrow. I also find that upgrades are generally consistent albeit in longer time frames. So "I personally" wouldn't stash a huge lot. "I'll" do my testing, buy some film and go photograph the gardens of Japan, or some such subject of interest and consider the experience an opportunity to record the wonders of the world. Perhaps that will translate into creating a travel book or a photo book, but for sure I'll be richer from the experience of meeting different people. So for me it's not the potential in the freezer that counts, it's what it produces in the life. Like I say, a different response.
