I have the Prosoft Binders one for my digital print out as it makes it very easy to print and add the pages into my "paper" one as they fill up myself.

you can then print it out to keep a bound version as well. Now i keep fully digital (I personally use log ten pro-x) you can sign digitally for endorsements and it will print logbook entries with CFI signatures etc. I used the Jeppesen pro-pilot logbook when i still kept a paper handwritten logbook.
