You really have only one choice and that is the Perkins Braille Writer. I don’t think you are looking for the electric one.

You can find brand new ones at Perkins Store. Price is around $900.00

Here is the web URL to the Perkins Store for Braille Writers:

You can find people selling secondhand Perkins Braillers ranging in price from around $250.00 and I have seen some going for as high as $400.00. Ads are usually found on blindads a listserv found on groups.io, and you can find ads in the Braille Forum from the American Council of the Blind and the Braille Monitor from the National Federation of the Blind.
