After looking into gear for some time i heard the standard advises:
Also I heard the different methods how to determine price of gear.
... and so on
Looking into the market, i was confused how old gear could still hold such a high value sometimes, regardless of jump numbers and age! So I did the math to evaluate the offers that are on the market. I am open to suggestions, but i feel that "used=cheaper" is simply not true, due to the lack of people buying new and market price that results from that. Therefore, I think that skydiving gear may be a great investment, as it is not affected by inflation at all!
Here is my calculations. Feel free to correct me
