i was going to pull the trigger on the Amazon Oral B Triumph 5000 but the wrong voltage thing spooked me.
From what I can see the only difference between the 4000 and the 5000 is the little lcd display. The lcd display doesn't seem all that useful, I don't think it would get between the teeth at all.
This isn't the cheapest it has been, but it seems like the best price currently.
I called good guys to price match and they said it's below cost/they can't do it. So it seems like a good buy/bargain.
