braille displays

[Scott Howell]

Folks,

I have a question about braille displays. First which displays work with 
Linux, second is it very difficult to get such a device working with 
Linux, third which software/driver etc. is best for accessing the 
device, fourth I assume any application which is console based will work 
with the displays, and finally what are the expected price to pay for a 
decent display and where should I consider looking for one if I choose 
to purchase such a device.
