Hey Curtis
The only reason I'm not using the SeedStudio CT myself is that I can get a CT sensor from efergy in the uk for £7.50. I know that Hendrik who has been building the circuit has used the seedstudio sensor and had good results with it. He found the internal burden resistor to be 62ohms I think and the turns ratio to be about 1:1900 which works out to be pretty close to 1V at 30A.
Hope that helps
