A guy told me this one time: "You can have it fast, you can have it cheap, you can have good quality. Choose two!"
Get the Shureido. Or find someone on Okinawa to get you a custom made pair.
I have had a quality pair for 15 years. They have been dropped, thrown, used for digging, chipping away a stone abuttment(don't ask), banged in training against other sai,bo,swords, machete's etc.,etc.
Spend the money. It's a better value to spend $80-$100 now and they last forever, than to spend $30 dollars a year for the next 10 years on a low grade weapon.
