Query: Sonicare PL4 (4700)

If you don't own one of these, you should. I bought the Advance 4700 for my son and I tried it. OH MY!!!! I'm hooked! The only negative was the brush head and handle was considerably larger than the Elite 7300. I see the price has dropped on the 4300 to around $79. A friend has the 7300 and the ergonomic design of the handle and skinner brush head makes it really much more comfortable. But on the other hand, some people like larger things stuck in their mouth, so it that's the case, go for the $20 savings and get the 4300. All I can say is, I want to go brush my teeth right now. You won't be sorry with either!
