https://marketplace.tf/items/tf2/30180;5;u17 - Sold for $100.09 (Keys were $1.73 each, so this sale is 58 Keys)

Even though the Tundra was in-date when the sale occurred, it's still a good idea to look at its recent sales in case the price has changed since.

https://marketplace.tf/items/tf2/30976;5;u17 - 2 sales at $159.99 (high), 2 at $92 (low), 2 at $140 (79 and 83), and 1 at $149.99 (85 Keys)

https://imgur.com/a/zLetMX3 - The 83 sale was capped by the buyout of 70 Keys

Taking 60 - 85 for the Tundra makes sale 1 around 80 Keys.

Current sellers would support 124 being too high - https://imgur.com/a/mTH7tUU

I would exclude 58 as low and 124 as high, resuggesting this at 80 Keys flat.
