I am a fan of MBG. They are very bright, light, and very durable.
I have a Spot-Hogg sight and really like it the .019 pins are perfect.

Switched to a Black Gold 4-pin (can't remember exact model) last year. Been happy with it so far.
I switched to Sword sights several years ago and love them! Definitely in your budget.

I shoot the truglo ddp setup. It'll fit your budget easily. One tough sight I've ran it through the ringer has smaller pins the further out you get worth a look
