To be completely honest I think you're overreacting a bit Eric. I wouldn't sweat the issue of not being comp'd to attend. There could be a lot of reasons why they aren't comp'ing you such as your following may not be the market they are trying to attract etc. Also, in my opinion the best reviews are done on products and services that you pay for out of your own pocket. That has been my experience at least and I've done a lot of each. Good luck at the event and I look forward to seeing how it goes for you.
