Affordable, 500 to 1000 dollars will get you something good. Find what fits you, and your need, cheaper to get a gun close to what you want to end with then pay and hope you get the right part to make it what you want.
Adjustable sights are good. NORC are OK but will always be a NORC even with 1000 dollars dumped into them.
