Ask DN: Designers, what is your sketch book of choice?

over 9 years ago from , Designer & Dev

For those of you who still love the feel of a pencil/pen and a paper to sketch out your ideas, what is your choice for a sketch book/pad?

I'm looking for something that is easy on the budget, something that's bigger than pocket-sized and allows me to remove pages(perforation/spring binding), which doesn't deteriorate its binding. Suggestions? Thanks!
