T9 Turkey Red Questions
 

Hi. I am in the process of building my T3 baseball set and started looking at the boxers in the middle there. Can anyone give some basic info on them like which ones are tough and not, what are some average prices for said cards (I will only be doing SGC graded as a point of fact) and what is a good source or two for digging them up (ebay has some but most are the usual PSA graded and what seems to be overpriced).
Any help would be greatly appreciated and thanks!
