Hey man well I myself was going to take the T206 plunge but decided not to but this site below is very helpful. Also the book, The T206 Collection: The Players & Their Stories is a must have for any hobby collector.

The site has everything to do with the T206. Great checklists and such. As I was told buy what you can when you can. I myself am all about having all my stuff graded by one company but others here say if its a good price buy it. As for raw graded stuff I am truly not a fan but hey to each their own. I wish you best of luck on this MONSTER. Your going to need it.
