Ok, so i09 had this short article http://io9.com/this-may-sound-a-little-trite-considering-how-gorgeous-1665951640 regarding a supernova in a galaxy far, far away. Personally, I think the shot is GORGEOUS. Anyone know of places where I could get it printed, if I can get my hands on a hi-res shot?

I recently had them print a mat for me. The quality is pretty decent, but definitely pixelated up close.

You may want to email them and ask that they send your banner in a mailer tube or somehow stiffen the banner in the packaging. When I got mine, it looked like UPS had run the box over, and the banner had been loosely "fold-rolled" to begin with. The resulting creases are fairly deep, and show through the image.

If you're looking for a super-clean print, I don't think bannersonthecheap is gonna work for you. If you want a nice looking image for very little money, go for it!
