This happened 3 years ago.
I switched to the Sire Ratings book from Progressive Handicapping for less than $40, which includes postage. Jim Mazur runs it.
I used to buy the Tomlinson book, but when he sold the data to DRF he stopped publishing it.
Then I went to Dan Serra's book, and that was discontinued when his data was used by Post Time Daily pp's.
Then I went to the Bris book until 3 years ago.
Sire Ratings uses A+ through F ratings like Bris did.
++++++++
For those who use Bris premium pp's I made a chart that converts their number ratings to letter ratings.
Take note, this is created by me and I've been using it for about 6 months. This is not written in stone and I may want to tweak it myself at some point.
A+/119 and up
A/117-118
A-115-116
C/106-108, the only letter grade using 3 numbers
D-/98-99
F+/96-97
F/95 and lower
I used + and minus for each letter if you want to complete the chart.
I use mostly for distance and to compare off track and turf to the Sire Ratings book.
