I have used them all and can tell you with certainty no matter what you get the motors will eventually give out. I prefer Lucky or Mojo spinners with the solid plastic/metal wings over the corrugated plastic ones. The flappers are good, but I prefer the spinners over them. I have been using the baby mojos for the past few years and they are okay, except for the corrugated magnetic wings that you have to baby. You can get the baby mojos online at Walmart for $60 and a remote controlled on/off switch from 12 volt.com for $13
