Okay, so you know his form is Irish until 2007, on the flat for Jim Bolger, great trainer. Had sea the stars. He moved then too jumping, that suggests he was sound and right.
He's had a few runs over hurdles the orange ones, but not big chase fences, looks like then he's been put back on the flat to freshen up. I've never heard of his father but you can look up the prices and what happened to his siblings on tattersalls.com or his mothers offspring by searching for dams on the racing post site. I'd want to check him for wind sucking, and I'd want a vet to check his legs. Have you checked for splints etc? His Irish trainer is a very respected man, so he will have been well looked after but I've not heard of his last trainer, but if you go on directory of the turf you could call or email them to enquire; nothing stopping you and most bosses I've had like a update on their horses.
For me it would depend on the severity of the rearing. Are they little excited tears or full on blind could go over rears. Race horses (ex) are generally in fairly cheap. I was recently offered one for £300. Absolutely nothing wrong with her and had I not just had ds I would have probably taken the risk!
And some of the ex racers I've sold at ascot sales have been brilliant rides, and sound just useless at racing or heart not in it and have only made 300, lowest bid. Gone to nice private homes, and 2 went to play polo. So I would go for it personally if he is sound, if he's not and you want a TB- look at redwings and great wood. They are fab
Definitely get him checked by a vet and I would insure him at least for the first year in case their are hidden problems which could turn out costly.
Many ex-racers go extremely cheaply, sometimes just for free (matter of phoning round the yards, most owners rather have them going to a nice home than the butchers).
I personally would look for one who doesn't rear, but that is because some do go over, which clearly is very dangerous. Plus at the moment there are so many who will be off loaded, that you will easily get another TB (really just pick up the phone and ask racing yards if they have any horses the owners are planning to dispose of).
Maybe. Racing is bloody hard on them though so that would be my worry, tendon issues and the like. But he might be great, it's a gamble. Rearing spooks me a bit, they can buck all they want but rearing can so easily turn nasty.
There are lots of cheap - or free - ex racehorses around either direct from trainers or rehomed from retraining centres.
As Makingitup says he was originally owned and trained by Jim Bolger who bred him from a stallion, Lil's Boy, that he had owned and trained himself.
He wasn't much good so they sold him to Brendan Duke who used to train here but now lives back in Ireland.
He ran poorly in a couple of hurdles so they put him back on the flat in 2008 as a 4yo. He did managed to be placed four times in a row on the all-weather in the early Spring of 2008 - from 7 furlongs to a mile.
He was 2nd once - only beaten a neck at Wolverhampton - but never actually won. His last run was at Salisbury for a girl apprentice in May 2008.
During his racing career he wore cheek pieces, blinkers and a tongue strap so they did everything to try and get his head in front!
He is 9 now and Racing Post doesn't have any record of him going through the sales ring. He is a half-brother to three winners.
I'd be a bit worried about the rearing.
Jim Bolger is indeed a genius of a trainer but Sea The Stars was actually trained by John Oxx.
Price wouldn't be a worry so much, but definitely get his legs (and back) checked. Ideally get the legs scanned for possible tendon or ligament damage. Looking at his race record, he didn't earn a lot, so probably why he was retired.
He seems to have been evented from 2009 to 20011 (only up to BE90 looking at the British Eventing site )but I can't find any competition record past that date. There are a few retireds on the eventing history and it would be interesting to know if there have been many since, and why.
That said, ex-racers really can make really nice riding horses, so, pending the discovery of any major injuries and depending on 'rear' factor I'd say go for it.
