Many good sights can be had for less that 100$. You've got a good list started to look at. I'd also recommend Vital bow gear vertical sights. I own a trapper and absolutely love it. It's a high quality well built sight.

As for pin selection, I'd suggest sticking with a sight that has a .0029 pin for hunting. I'n low light you'll probably want as much "glow" as you can get. If you are shooting competition or 3-d you may want a smaller .0019 pin for longer distance shooting.

Hope my opinion is helpful....
