SABR's website is pretty good. VCP is good for card prices - several t206 specific pages are good for t206 research. I suppose it depends on what you are researching - I second the aggravation with AI generated answers - it's great when it works, but a huge pain in the ass when it misunderstands what you are looking for. AI is tough for research since you have to know enough to figure out when it's hallucinating.
Fastest way to get the correct answer is likely to post incorrect information here on the forum - and you will likely be promptly corrected with supporting detail
