its cheaper to pick up and old game or just buy some off of Ebay
I use some AA guns and Factories from my 1984 game. I like the white.
You have a good point, just don’t forget to consider the weight that time and convenience has. The historicalboardgaming.com site is very convenient if you just want a few things, especially pieces from the new Europe and Pacific 1940 boards as those are minimum $60 per game. You can also buy sealed (unmolested) IPC’s, or brand new custom-made IPC’s on the site. I personally appreciate sealed items if the premium is reasonable, especially things you can’t really wash, like IPCs.
Before historicalboardgaming.com recently opened shop I spent $25 (shipping incl) on a whole set of factories and AA guns still on their plastic trees, along with 2 sets of sealed IPCs (from revised I believe). I then found a 1986 version of A&A 2nd opened but never played with for $20 on kijiji. I consider these to be very lucky buys which took lots of hunting, where historicalboardgaming.com has the items in stock now.
