John Hyre materials

Wanted to see if anyone has purchased/used John Hyre’s materials? I’ve listened to his audio for business entities and i’ve found it to very imformative. Any thoughts or concerns anyone may want to contribute?

Thanks in advance

His material is more reasonably priced than the typical guru’s material.

What other guru’s are there? Anyone recommend someone for either business entity and/or bookkeeping instruction? Also are there any other audios I can listen to that I can compare with John Hyre?
