The Killian (toronto) is fairly tough and you got a good price on that one--he is probably among the toughest 75-100 cards in the set but easier than the two mentioned above. The one I was referring to was the Jimmy Austin (St. Louis) and I was the high bidder on that one--the New York Austin is only moderately difficult but the SL version is very hard to find. The funny thing about the Austin is that I was able to find a E270 Tin Top before I was able to find the E254 St. Louis version.
