If near neutral is good enough, Kodak Flexicolor fixer (made for some kind of colour processing but quite suitable for black and white film and paper) is often significantly cheaper than "black and white" fixers. Its pH is around 6.5, so not far from neutral.

I use it since the demise of Agfa FX-Universal which was sold as a fixer for colour and black and white. Its pH was around 7.5 (so it was truly alkaline, but not much).
