Here are just a few of the resources I have  personally used and can confidently recommend.

NOTE: Only resources I trust and highly recommend will ever make it on this list!

KATHY RECOMMENDS:

AudioAcrobat – A phenomenally versitile audio/video recording and publishing site great for experts and beginners alike. Makes recording and publishing your recorded content a breeze. Excellent product creation tool. Free trial available. 
 

MicroNicheFinder – A powerful, user-friendly keyword selection tool that cuts your keyword research down to a fraction of the time. What used to take me hours now takes minutes. Great training in the 5 free videos you can watch even before you purchase.
