I’m paying about $800 a year for my climate-controlled 10x10. I can keep 2 big shelves of parts and 8 games in it. The vast majority of the pins I store are 80’s games that I’ve spent weeks or months restoring. The place didn’t raise my rate at all this year, which surprised me. You definitely have to be prepared to move every 2-3 years. One time I had my mom rent the unit next to mine, same size, for $100 less. I just moved my stuff with a hand truck, only took a few hours.
