Best place to get 200A CT's

I need two more 200A CT’s.
Where is the best place to get them?
Just order them directly from Accuenergy?
Model: AcuCT-H100-200:333

Will I need anything other than the connector if I buy them from Accenergy?
The IoTaWatt page mentions “TVS diode protection”, Is that in the CT, or do I need to add it?

I believe the price is Canadian Dollars.

Thanks, I just bought a set.

Any idea where I might be able to get a set in Australia? CircuitIQ will ship to Australia, but - as you can see - the shipping costs are an absolute joke…

I’ve sent an inquiry to Echun.
