better grinder for pour over?

I know high end grinders are probably worth it for espresso, but for pour-over coffee does it make that much difference? I use a Capresso Infinity at either fine coarse or medium coarse and that's about it. Visibly the grind size does look a bit variable to me. Since I'm already in conical bur territory here, are higher end grinders really going to make a noticeable difference in my pour-over brews? If you feel strongly the answer is yes, I'm also curious what you would recommend (but please don't bother naming anything over $500usd unless you provide a link to a used version that is in that range).
