Pricing Questions Regarding Older Items

[Swanngrinder]

Have a couple questions for folks out there into the older stuff, as I am currently looking for a 16710...and having been away from the hobby for about 6 years or so, going through the prices, availability, and secret handshakes/voodoo/bloodsport AD processes (not relevant to this conversation, but prominent in my studies) has been little confusing.

I understand the new stuff on the second hand market went to insane heights over and after covid and is currently(potentially/maybe/I have no idea) on the downswing.

How have these price swings over the last few years affected the second hand market for older stuff? For example, did they rise in tandem with the surge in popularity of the newer releases, and was it tit for tat or relatively minor or even more pronounced? I really can't recall the price in the second hand market for these 6 or 7 years ago. Do you think the price of the older/borderline vintage stuff will ngo down as the market for the newer stuff normalizes, or do the two categories operate somewhat independent of one another?

Basically I am doing the "Should I start taking this seriously?" dance, while wondering if there will be more examples to choose from in a year or so at better prices with less pressure to make an immediate decision over a specific piece.

Also, how has the surge in popularity for the hobby affected the availability and cost of parts for the older models when maintenance or repairs come up?

Thanks!
