A few items that are pricy to replace now (some would require refurbishing).
Roger's LS3/5a's purchased in 1978 for $500 + the cost ($130 ?) of a 1-way plane ticket from London to LAX for an X-Girlfriend.
Nakamichi 700ZXE that I paid $75 for in perfect condition and sold 20 years ago for $600, or so, as we recently unearthed two large boxes of my wife's cassette tapes.
I do miss my vintage Dynaco and Mac tube gear, but much prefer DH/SET to them (mainly miss the PAS preamps when running tape/line through them - phono was so-so).
