Seeing as though you're out and about, and might not have to pay for shipping (which is a huge part of Vinyl pressing costs).....it really wouldn't cost all that much. For those people taking about profits: if these things sell for more than $3 or $4 each, there'll be profit.
Just cuz you buy it doesn't mean you have to play it. In fact, it'd be kind of stupid to play it. I'm sure there would be a digital copy available somewhere (ahem), so you could leave your LE Syko Vinyl untouched and on the shelf.
Can't really speak on Opportunity Costs (vinyl side project vs a regular CD), because Syko has been making 100,000 a year in Opportunity Salary for a few years now. So yeah, most of us (myself included) will buy anything at this point.
