It is correct that the 250kv is a standard offering, and the 210kv is a custom wind. Last time I talked to Innov8tive, it sounded like they were ordering more 210's as they are popular among us. They got more 250's in but I am still waiting for a 210.

One thing to note is that the new generation, i.e. made within the past month, should have a ring molded into the casing to prevent the magnets from pulling out. The last ring was pressed in and did nothing.
