I like that one too! Fog, is there anything you can do to make Retro Kevin stand out a bit more so its easier to read when its being used as a small logo? Like maybe make the text black or something? Just a thought...
I learned cursive in school but I so rarely use it I can't remember how to...
The first one is probably the best drawn out of the lot but it doesn't look very retro to me. In terms of being a logo that really represents "retro" Id say your current logo is the best. Just my .02
