Logbook Pro works well for me. Google it at your leisure.
IMO, the sooner you get on to an electronic logbook the better (as long as you're going to do it anyway.) You can transfer your paper logbook totals across with a basic summary, but it's nice to have the full details of all your flying in your electronic logbook and it can take a while to do. Do it now rather than next year and save yourself a year's worth of data entry.
On that note, Logbook Pro have recently started a service where they will enter your logbook information for you (I assume you mail them photocopies or something,) for a fee of course. Other companies may do a similar thing.
