Given that the difference between the cheapest and most expensive logbooks is probably 5 minutes flying time.
May as well buy the one you like best - everything you see in the shop is likely to be perfectly acceptable. Do buy a commercial one if planning to do more than PPL flying.
And yes, electronic these ways is the way to go. I'd suggest as-well, not instead. There are various commercial products out there - or create your own if you have an IT bent; I run mine in MS Excel, although there are numerous other ways to do it. Authorities are generally perfectly happy to receive certified printouts and don't necessarily require hard copies, although having a paper logbook for master copies of stamps and signatures is useful.
If you want waterproof - keep it in a plastic bag. If you want hardwearing - many companies sell leather covers, just make sure you bought one that you can get a leather cover for.
