I ride with a coaster brake, but would recommend rim (hand) brakes. The coaster has got me a little nervous at times; but the bike is not a daily rider nor is it neccesary transportation at any time....just for fun.
I also like single speeds (or very few gears), as I think it looks better, frees up the handlebars a bit, drops weight, is easier to maintain, and if you get a good gear ration you shouldn't have to pedal too hard or too fast to get 'er started or if she dies and you gotta pedal it home.
