Honestly, I totally get the Terapeak fatigue. Ive been doing this for a decade and while its great for deep dives, it feels like using dial-up when youre trying to scan through hundreds of LEGO sets. You need something that just pops up without all the extra clicks. I've tried many extensions over the years, and mostly they either break after an eBay update or they want like thirty bucks a month. If you want something that actually stays on the page, you gotta look for tools that inject the data right under the listing title. Heres what I usually tell people who are sick of clicking every single link:

• Look for extensions that pull from the eBay API directly so the graphs dont lag
• Check if they handle Best Offer prices because those are huge in the vintage LEGO world
• Make sure the US data is actually filtered correctly Honestly, PriceDropCatch is the best way Ive found to track Buy It Now prices without any extra clutter. It really helps when youre trying to spot a deal before someone else snags it. I basically leave it running in the background while I browse. For the graphs specifically, some of the free ones are getting buggy lately, but there are a few niche ones that still work for the US market. Just watch out for the ones that slow down your browser too much. Vintage stuff moves fast so you cant have your tabs freezing up on you every time you scroll.
