I was wondering where I could purchase a good quality electronic toothbrush.

I prefer the cybersonic 3, but other brands can be considered if they have a similar amount of strokes per min. (20k+ strokes per min). The Oral b pulsonic looks promising.

I'm having a difficult time finding these online.

Online? If you want sent here try EBay.

Tops sell a Colgazte one which is quite good and very cheap.

Don't know where you are located but have seen the Sonicare at Central Department stores

Braun Oral-B at Central Dept. Store, about B1000.Good 'nuff. Buy brushes on ebay or amazon. Sorted.

I haven't been able to locate a Philips sonicare in Thailand. Anyone know where? I prefer their cleaning power to the Braun.

I also could not find Philips 3 years ago and ordered on Ebay. Not sure if available now or not.

e bay put in sonicare china see what comes up try Korea hong kong too

The no frills ~1K baht Braun is the best available deal. At Central Dept stores.

Sure you can spend 4 to 5K for the Braun with all the features.

The waterpik is great idea also. I found a dealer in Chiang Mai that sells and services them.

Conice is shop/company name and located inside the moat near the north east corner.
