At risk of sounding blunt, I do want to ask: have you tried several fixed-width fonts, or have you just used whichever is default on your system? In my experience, there seems to be no issue seeing where there is a space (not even for a split second) with well-designed fixed-width fonts. In fact, for me, it's more apparent, as spaces tend to be wider in fixed-width fonts, being the width of the widest character.
