Is there a workable bin format font file?

Has anyone tried any of the third-party font bin files? I've tried web converter tool as well as DotInk app (paid $2 for it).

The web converted fonts (I tried Bookerly) are horrible - the letter spacing was gigantic no matter how I adjust it. The words are blurry.

The font from DotInk are readable, but I can't get apostrophe mark right (it takes one letter space), and the spaces between words are again huge.

Does anyone have a workable .bin format font file?
