Questia--Researcher Heaven.or Hype?

I would love to be able to answer that question but I can't afford the subscription fee to check it out. But if it is as comprehensive as they are making themselves out to be, I would dearly love to. I am putting it at the top of my wish list for when my efforts here and here and here pan out into some kind of monetary remuneration. I would love to review it on Joyread. But until then, does anybody out there have experience with it? Comments are open.
