She may not be top class, but you know you've got a good deal when the horse you bought for $6000 is fast enough to race against one which cost one hundred times that amount.

That's exactly what trainer Terry Croft has discovered after he bought two-year-old filly Harada Tat Tat at the Sydney Classic Yearling Sale this year.

Now the youngster is set for her maiden start in Saturday's Gimcrack Stakes (1000m) against the Gai Waterhouse-trained Sugar Rush - a $600,000 yearling.

Harada Tat Tat impressed in her barrier trial at Warwick Farm, finishing second behind Sugar Rush, who has been made favourite to win the Gimcrack.

"(Jockey) Corey Brown was very taken by her at the trial," Croft said.

"He said, `don't get me wrong, I'm not saying she's top class, but I'm saying she'll win you races'."

The filly's performance in the trial was enough to earn her a place in the Gimcrack field.

"She was only sort of half-fit going into that trial. She just wasn't really wound up," Croft said.

"We were just hoping she would qualify for this race."

Croft says snaring the filly for such a bargain was simply a matter of luck.

The owners had been prepared to pay more than double than what they did for her because she came from a "pretty good winning family".

"There was nothing wrong with her," Croft says.

"I don't know why she was so cheap. I thought she would bring in a lot more than what she did.

"We were just there at the right place and the right time."

Besides the might of the Gai Waterhouse stable, Harada Tat Tat will also face off against fillies trained by Peter Snowden, Peter Moody and Graeme Rogerson and Lee Freedman.

"I expect her to run a very big race," Croft said.

"We'll be happy if she finished in the placings, but even if she didn't win and pulls up alright, we might consider taking her up to Melbourne for the Inglis Challenge in three week's time."
