I've been thinking about investing in some Incra Rules and have been tempted by some of their sets. But, I can't help wondering... do I really needed 3 different sizes of each rule? I'd hate to spend $200 plus on a set of rules, only to use a few of them.

So, I'd like to ask: If you use Incra rules, which ones do you use the most? What do you think are the essential ones to purchase? Thanks in advance!
