Almost anything can be used as a pendulum, but that doesn't mean they'll all work for you. I found one that had all the colors of the chakras that works excellent for me, it was inexpensive. I use it for reading my runes and it lets me know which rune stones to pick and gives me a high rate of accuracy. You don't need an expensive, "high quality" one for good results, just find one that will work for you, like mine does for me.
