I started with waturf.org.au You can get past results on WA races going way back in a csv format. West aussie racing suited me. It wasn't corrupted by too many "outside" horses with form that I didn't have coming in and winning races. And not many heavy tracks which can throw a spanner in the works. Since then I've gone on to NSW races which you can get results for from racingnsw, also in csv format.

A word of warning, I don't know about results you pay for but there are mistakes in a lot of the free stuff I've downloaded from various places. I spend more time fixing data than I do working out ratings.

Best of luck,
