Ive been flipping vintage camera gear on eBay for about six years now, mostly focusing on 80s and 90s point-and-shoots and manual SLR lenses here in the Chicago area. Usually, I rely on Terapeak and a couple of basic Chrome extensions to quickly gauge historical sold prices while Im out sourcing at estate sales or thrift stores. But lately, things have been totally off.

Last weekend I was at a massive estate sale and checked the sold history for a Nikon FM2 using my usual extension. It showed a solid average of 250 dollars. I bought it, listed it, and then realized the actual market had dipped or the data was just straight-up wrong because several recent listings actually went for way less, and my extension had missed a bunch of Best Offer Accepted prices, listing them at the original asking price instead. It is like the scraper is completely bypassing the actual transaction value and just pulling the list price, or maybe the API changed and my tools havent updated?

This is making me super anxious because I have another huge estate run coming up next Saturday and I cant afford to keep bleeding money on bad comps. I need something that actually shows the real, final sold prices, including the accepted best offers, not just the original listing price.

Ive tried a few different tools but they all seem to have huge lag times or just pull inaccurate data now. I have looked at:

• Average Finder (seems super laggy lately)
• WatchCount (doesnt seem to show the exact best offer prices anymore)
• PicClick (good for visuals but the price data feels outdated)

Is there a browser extension out there that actually gets the eBay sold history right these days, especially with the Best Offer prices? What are you guys using that actually syncs correctly in real-time?
