I chose Northstar Aviation References (northstarvfr.com) for the FAR/AIM tabs because of their excellent reputation. It is my honest opinion that their reputation is well-deserved. The instructions were very easy to follow, and the video that was referenced was very helpful. I also greatly appreciate the sticker with the index that I placed on the inside of the front cover. The tabs make it very easy to find exactly what I am looking for, and they look great.
I especially like that the tabs are color-coded based on whether the regulation they are referencing apply to private pilot, instrument rating, commercial pilot or CFI, and that it includes color-matching dots that go next to each regulation that the tab covers (I got the private pilot/instrument/commercial combo).
I highly recommend these do-it-yourself tabs to anyone who wants to tab their FAR/AIM. They do cost more than other options on Amazon, but I found those to be haphazardly put together with multicolored tabs that mean nothing, some of which have dark text on dark tabs (unreadable). Northstar Aviation References makes a FAR SUPERIOR PRODUCT that is worth every penny and then some. Thank you!
