Cranbourne trainer John Price has something of a reputation for finding a bargain buy and his eye for a horse is again tested at The Valley on Saturday when rising four-year-old Frock 'N' Bling makes her debut.

Price, who paid just $4500 for the filly at the 2015 Magic Millions Sale in Adelaide, said on Thursday that the horse has shown ability at the jumpouts but he is unsure how she'll cope with raceday pressure.

"She's very fickle and fragile and I'm just having a throw at the stumps," he said. "I think she goes alright but it's just a throw at the stumps because Moonee Valley can be a tricky track.

"She's had a few jumpouts and she's gone well in all of them but she's never been able to hold up to get to this stage.

"I think she'll go well enough to get amongst them.

"I'm very, very confident she won't embarrass us. It's probably a bit foolish but bugger it, that's what we are going to do. I'm hoping she'll surprise us."

Price paid the $4500 for the yearling on behalf of owner Shirley Prosser at the same venue where he picked up the smart sprinter Wise Hero for just $10,000.

Now a winner of $180,000 in stakes from just five starts, a Spring Carnival role is a possibility for Wise Hero.

"After June 24, we'll have a real good sit down and decide where we can go," he said. "If he can win at Flemington over that 1100 (metres), we'll sit down and try and target some races there.

"I'm pretty certain he's all set to go. I think he's fairly much up to the mark.

"I learned a bit with him the other day. He trialled much better than I thought he would. He showed me he can show his best when left on the fresh side."
