I have attended most of the Lone Star Audio Fest events, and will attend this one. I think it's a great opportunity, especially given the unheard-of reasonable price for the show.
I would very heartily recommend Lone Star to any manufacturer who isn't up for spending the big bucks for Rocky Mountain or Stereophile or CES/THE Show. You get internet buzz for your products, and you can link to that buzz when you have e-mail conversations with people. You have a reasonable chance of making a sale - and actually making money that weekend (you'd have to make a much bigger sale to break even at one of the other shows). And you will make friends and business contacts, including contacts with members of the audio press (who will have enough time to actually sit down and listen to your stuff and get to know you). That can lead to a review.
My wife and I do the show together, usually sharing the room with NTV Amplifiers. Here are links to some eye candy from the 2008 show (we missed 2009):

The price and policies make it totally accessible to anyone out there in DIY land who would like to showcase his or her handiwork. And, for anyone contemplating crossing over to the Dark Side and becoming a manufacturer, here's your chance to put your stuff up against the pros and maybe raise a few eyebrows... and perhaps transition from hobbyist to part-time manufacturer. Or just enjoy and promote your hobby (speakerbuilding, ampbuilding, vinyl, whatever) for the price of a hotel room.
