Hi Phil,
the most people have there own favorite length and weigth. That can be 60cm to 75cm length and different weigths. Diameter can be 2cm to 4cm. The thinner one is good to perform and practicing moves and techniques on lower level and the thicker one is good for practicing powerstriking.
My recommendation is to buy rattan in the length of 270cm and cut it yourself. Internet-Shops are often to much expensive. I bought my rattan at a company who makes furniture with rattan like sofas, seats and more.
You can save 80 percent and more by this way.
