I have two of these for sale NIB. I purchased three from the UK and kept one for myself. They are absolutely awesome and I wouldn't be without mine now. The model I have is the UK one which has a shaver plug and is multi-voltage (100-240v). Includes 7 tips and these are readily available on TM. RRP $229+

 

$195 each with $8 shipping nationwide, $12 rural.
