The difference is the ability of the plan to be invested in a more diverse choice of assets, including real estate.There are several quality providers of self-directed IRA services active here on BiggerPockets.  

They are committed to building sustainable, environmentally friendly spaces that promote healthy living.

It is actually unethical for us as REALTORS to promote our services as no-cost (it's in the NAR Code of Ethics).  

A diverse economy and steady growth offers various opportunities for all kinds of investment properties, ranging from vacation homes to house flipping to traditional long-term rentals.

I get geographic diversity which helps with reducing the risk that any particular city dies whether through economic or environmental adversity.

I call them "one economy towns".I like a diverse mixture so that if one business goes out plenty can prop up the local economy until that space is filled again.

I got on one of the webinars he promotes and paid $997.

They even dared to use us to promote their company on Facebook & Google.The Flipping seminar was very basic.

I don't know if I'm allowed to post it here and don't want to get in trouble for self-promoting. 

@Dmitriy Fomichenko has requested that the provider of the so-called "eQRP®" clarify what type of plan he offers and he's been given the opportunity to speak for himself.As I have personally spoken to many individuals that have this "plan" - or promote it - it's likely that I can answer the question.
