Mag Drive Pumps

[Latinreefer]

Does someone know the difference between Danner Mag Drive, Pond Master Mag Drive and Mag Drive Supreme?

I want to purchase a mag drive but came across these three options and they are priced differently.

Thanks for your help !!

Can't remeber what the supreme was, but I do know the pond master has an absurdly long cord. Obviously for placing in pond where you need the length.
