I'm sure this varies depending on available storage space, but I'm wondering how much gear you like to have ready in advance, and how you decide how much to maintain.

How many extra boxes with frames do you like to have ready?
How many for brood, how many for honey?
If you use wax foundation, how far in advance do you put it into frames?
Is there a ratio of gear-in-use to gear-on-hand that works?

Last year, I found that I was caught at times without gear ready, and it really screwed me up. I was busy with work, and then I needed gear, and I had to find time to build it and get it in place. I hated that feeling, and I want to avoid it in the future.

So I'm interested in your thoughts on the subject.
