Hi Barny,
2 of the best are

racing service.com.au (Mick Fagin) allows you a free trial.

lucky88.com.au
(free)

Both give excellent summaries of their bets prior to the race.

Hope thats what your after.

In my case I review whats on offer with all of them (not just with these 2) and then make a personal judgement as to what I eventually go with.

In my opinion its one own judgement of whats on offer that will make or break one as a bettor.

Cheers.
