I went to look at a horse last year. They forgot my appointment, but thankfully Daisy was there having driven 2.5 hours! I only tried one and have to say she was very well schooled and nicely uphill. She had swollen back legs from being in 2 days which put me off a little. (She prob wouldn't have had, had they remembered me coming!
).
They tend to have a few horses you can look at, which helps. I think like any dealer go in with your eyes open, but think they try to be honest, as probably have a reputation to maintain. Also think they are quite expensive for what they are, but that seems to be the case when buying from a professional.
They have bought some of the sale toppers here at the sales in Ireland so wouldnt be surprised if they are a bit more expensive.They seem to have some nice horses though.
