I'd bet that anyone in the budget price bracket still has reason to opt for porros.
I can't afford roof prisms that give as nice of a view as my old cheap $40 Bushnell 10x50 porros. I find roof prisms inferior in view at up to 5x the cost of those 10 year old Bushnells. For hunting, I choose a roof just so it will stow well. But if I want great depth perception, with limited optical defects, I still opt for the cheap porros in that price bracket. If they ever croak, I'll probably get some Nikon AEs or Pentax WPs
