Depends where you're going - if you plan on going professional (or just flying anything north of 100 hours per year) I'd buy a commercial book. For a PPL flying under 50hrs per year - yes the little Pooleys books are excellent.
I just finished a 20 year old
Airtour (now Pooleys) commercial logbook off, and designed and made my own - but the Pooleys one, would probably still have been my favourite if that wasn't possible.
And run an electronic logbook AS WELL - it does the sums for you, and provides a reliable backup.
