Unfortunately the majority of Sadlers Wells offspring are standing in Europe; so it doesn’t help anyone in North America who wants to dig into this line.
POWERSCOURT stood at Ashford in KY for awhile but in 2010 he was sent to Turkey.
GALILEO is not available in the US but there are a few sons of his here. Always a fan of him; tremendous stallion and his dam is by Miswaki!
PERFECT SOUL; stands in KY at Darby Dan.
Sadlers Wells had a long list of offspring sired by him and out of mares by ALYDAR. I know several have raved about the ALydar line horses for sport. At least one of them was a successful steeplechase horse and raced in three countries. DOUBLE LEAF.
BULLET TRAIN is a good son of Sadlers Wells. Last standing at Crestwood in KY. His dam is by Danehill. He is a lovely looking horse, not super heavy or cresty

SLIGO BAY is also a neat choice. Sadlers wells out of HALO x Herbager mare. He stands at Adena in FL
SADLERS WELLS was also bred heavily to daughters of Secretariat. 29 offspring of his are from daughters of big red. Perfect Soul being the most notable.
There is also DESERT SECRET who was last standing in CA in 2006 at an affordable price. He was standing at Eastridge Farm. He would be quite old by now so not sure if he is still alive
Saddlers Wells was mated heavily to daughters of SIR IVOR resulting in such sires as EL PRADO,
