I am lucky and have a storage unit in my office but it's getting filled fast. Hard to seek out books because of space, but it's dry.
I wouldn't feel comfortable putting them in my garage.
I have rented a 5 x 10 storage unit that is climate controled. It cost me $85 a month but it has been worth it. My current plan it to take a part of my garage and built a room in it with raised floors. Then I can have my stuff at home in about the same environment.
Before I sold off and gave away all my comics I had them stored in File Cabinets...
