Whislt not strickly speaking anything to do with my collection, this is an impressive site. The Millennium Falcon is in it, so it should count, right? www.merzo.net
Jeff Russell has created a web site where all sorts of differing SF&F starships are are shown next to each other. If you want to know how the USS Enterprise compares against an Omega Class cruiser or a Star Destoyer, this is the place. (You can drag and drop individual ships next to each other.) Unfortunately, It’s not updated too often as i would like to see other craft added. But It’s still an impressive website.
