As a newbie, I just use a regular spiral tablet and write everything (likes, dislikes, overalls, etc) in like in stone-age times. I will hopefully graduate to maybe a database of some type.
amazon has this for $29.99 usd, i have a hardbound steno book that is 5"x7" and has 150 pages...i paid $3.00 for it at staples.There is also a book/portfolio called a "Cigar Dossier" that sounds exactly what you are looking for. They are carried at alot of local tobbaconists....
