The reasons behind the "no trade show" rule are rooted in the very philosophy behind a Laser Enthusiast's Meeting. It is fundamentally a social event for laser enthusiast's. It is not a sales meeting, or a conference, or anything even remotely corporate.
Why? Because once you make it a corporate event, then the very people who started this whole idea (hobbyists) no longer have any reason to attend.
Seriously - ask yourself this question: Do you have any intention of purchasing a laser projector that produces more than 10 watts of output power and costs more than $10,000 in the next year? I suspect that the answer will be "NO" for the vast majority of PL members.
Now, with that in mind, do you see why it is important that the focus of the event NOT shift toward sales, and especially not towards sales of high-end projectors that most people will never buy? Why focus on something that is irrelevant to the majority of SELEM attendees?
There are plenty of trade shows that people can attend if they want to negotiate a volume discount on the latest commercial projector. But SELEM is not one of them. SELEM is more about people coming together to share what they have learned. It's about helping new people get started in this hobby - safely, cost-effectively, and enjoyably. And while fewer and fewer of our members build their own projectors these days, SELEM has always been a place for people to talk about (and show off) their work.
That being said, I welcome the chance for people to meet professionals from the industry at SELEM, but I always warn them that they need to understand the context of this meeting. It's about asking questions, getting answers, sharing stories, helping people, and having a great time. Companies like X-Laser and Pangolin understand this, and that's why they've been welcomed participants in the past. (After all, apart from SELEM, how often do you get a chance to get your scanners tuned by Bill Benner, or get advice on how to file a product report from Dan Goldsmith?)
This year we were approached by two projector manufacturers. They wanted to attend SELEM, and they were interested in bringing their projectors with them. I explained that if they brought their projectors, it would be expected that people (that is, SELEM attendees) would want to open them up, check power levels, run test patterns, and otherwise experiment with the units ON THEIR OWN TERMS. Then, once the initial curiosity wore off, we would put them up on a truss or tripod however we saw fit, and use them to augment the shows we planned to run.
Both companies were OK with that, and they agreed that while they would have someone on-hand to answer individual's questions about the projectors or the company, they would not expect us to block out time on the main stage for them to brag about their company (as you might expect at a trade show).
This is all new ground for us. In the future, if there is *LOTS* of interest in the idea of having projector companies demonstrate their products, we might set up a time slot in one of the upstairs classrooms for something like that. (Similar to what Pangolin does with their "What's New at Pangolin" presentation.)
But remember that Bill's "What's New at Pangolin" presentation was something that was specifically asked for by the people who attended SELEM in the past. Conversely, this whole idea of having projector manufacturer's attend (and possibly demo their wares) came from the projector companies themselves, and not the SELEM attendees. That is why we are treading cautiously for now.

PS: Evidently "mini-me" (Brad!) was composing his reply at the same time I was. And I do agree with his comments about the problems with vendors having undue influence on the event, as well as the need to avoid any needless sales-related drama. In fact, to avoid the undue influence problem, SELEM has steadfastly refused to allow any kind of corporate "sponsorship" of the event. We all pay our registration fee, so we get to control what we see and do at SELEM.
