Same device as the pocket pro - not sure what they charge to deliver to US though.
My choices are pretty similar to yours for readers - I use either my 505 or Hanlin v3 for choice.
The 350 is a very nice machine, page turn buttons are in a good spot, but there is no way to turn off the %^&@&$ touch screen when reading (Brush some dust off the screen and you change page) so my other half has swiped it and I've gone back to the 300 for portable reading.
