Cheap PK rings?

[ArcticChibi]

Hey, does anyone know a good and cheap PK ring I could get? I found this one called TMW PK Ring, but I'm not sure if it's any good.

I also found SuperMagnetMan magnetic rings.

The Wizard's PK ring is too expensive for my budget right now.

SuperMagnetMan is a great source.

I think I'm going to try that TMW ring. I haven't seen any reviews on it, so might as well.
