Been flying commercially for 2 years. Have had several paper logbooks. However I've (recently) changed to an electronic logbook. It has made my life so much easier. It took me about 3 weeks to move everything over from paper to computer. But now it works an absolute treat. I'm not going to suggest one electronic over another because they all depend on personal preference. But if your intention is to fly commercially then get an electronic one. You can then monitor all your hours including your standbys and total duty hours etc etc.
