Cheap alternatives to "cigar" beads?

It depends on what type of humi you have. I wouldn't use beads in a desktop. The gel is too convenient and works wonders in anything less than a 300 ct.

For coolers and cabinets beads are a must along with an electronic humidifier. That way they can act as a buffer.

2 drymistat sticks isn't bad but they also make those in rectangular elements too which have a larger surface area.
