It seems like there are "finds" of almost everything nowadays. The (espcecially) T231 and T214s have stayed elusive so far. T214s can be had but, you are right John, they just don't come up in mid-high grade too often. I have had these below for approximately 5-10 yrs.
To answer Bruces question though, D351 and D355 have eluded me so far....the quest continues.
