Ah, wow, this was my side project I'd been hacking on and off for the last couple months. However I'm glad to see there's a site like this out now, and that it doesn't charge any man-in-the-middle fees. Would be especially interested to know how they beat the chicken-egg...
My initial thought with the domain name was: "That's a rather specific thing to be selling... Side Projectors... Like creating a website selling just Dvorak Keyboards..."
I think the parent means that Side Projector sounds like some weird kind of a projector... as an optical device that projects an image onto a surface. That was my first thought.
I guess the market will decide what a fair price for any project will be? If the site works like I think it does (could not access it, server down?) I can imaging buying a project, working on it for a few months and then putting it back up for sale to maybe make a little profit and see some one else bring it to completing.
