I want a self-directed IRA. Is Pensco, Sunwest Trust, or someone else the best custodian for this type of...? - pensco trust

... Account? I mean the kind of self-IRA allows you to buy property, loans, etc., are not integrated into a broker, a discount or otherwise, or in a society of mutual funds. SUNW Trust and Pensco are the only owners who will manage this type of account. Those who had experienced one of these, or any of its competitors? All information and suggestions are welcome.

Thank you,
