At least on 228, we love getting new totes every year. We probably have almost twenty (non-broken) KOP totes and a half dozen 2003 Stack Attack totes. The KOP totes are all used to store FRC robot supplies (it's starting to look like -and be as oddly specific as- the
wall of totes from MythBusters) and the Stack Attack totes are given to each of our VRC/Savage Soccer teams. Our KOP totes are split between being stored in steel shelving and on rubber dollies (
like this), with the heavier totes on the dollies.
