Anyone know the step up in price for the higher end commercial Sony 515 / 510. I've never seen a company make something so hard to buy. I can't even get a price. I've seen the 615 listed at $100k, which makes it easy to dismiss. The small DCI DLP projectors aren't much more than the vw1100. The 515 was Sony's "small" DCI offering, with the 510 cheaper still. For most people, the vw1100 makes a lot of sense. But if I want a 16' wide 1.0 gain AT screen to watch 3D movies, then my needs are different. If pricing is in the stratosphere then I will need to make compromises elsewhere, but I hate to make compromises just to fit into Sony's predetermined opinion of what I need as a consumer. Customer needs a price check. How hard is that? Next to impossible as it turns out.
