I've used both LogTen Pro and Logbook Pro--both are good. To me, LogTen's interface, syncing, and reports are what set it ahead of Logbook Pro.

What I haven't found (yet) is a binder that doesn't look like some godawful high school arts and crafts project. All of the binders I've seen are cheap leather, with tacky gold trim; it more or less looks like someone went to Staples, bought a $35 chart case, cut it up, and turned it into an electronic logbook binder.

The only binder that ever caught my eye was the NC Old World binder which, for whatever reason, they opted to stop producing.



Throw some 35/40lb eggshell/tan paper in the printer, get Kinkos to cut and punch the paper, and it's a done deal.



I almost threw up.
