AI market analysis

For buyers

The current grey market range of $5,800-$6,400 appears inflated given the eBay median asking price of $4,966 across 44 active listings. Buyers should confidently negotiate well below $5,800, aiming for a price point closer to $5,000-$5,200 by leveraging these lower active listings as leverage. Now is an opportune time to secure this reference at a significant discount from MSRP.

For sellers

Despite a stated grey market low of $5,800, the eBay median asking price of $4,966 indicates strong downward pressure on active listings. To achieve a sale closer to the $5,800-$6,000 range, sellers must distinguish their listing with exceptional photography, a complete full-kit presentation, and clear provenance, avoiding direct competition with the race to the bottom. For quicker liquidity, pricing around $5,000-$5,300 would be more realistic in the current market.
