WTB: Tank Bag

[surf.seppo]

Hey Guys, I'm heading back out for the touring. My love of backroads and state highways means I need a way to hold maps/google maps directions. So a clear map pocket is a must. headphone port is nice, but not a necessity (no one yell -- I like cruising to classical stuff: Wagner, Tchaikovsky, Top Gun). Willing to pay a bit, but not too much, pretty please 

Anyone got anything? Or any leads on cheap deals?
