Sword sights are the best bang for your buck IMO. Great sights, you can choose your pin sizes in .029, .019, and .010 at no extra charge. You can even mix and match sizes. They also have lots of different color fibers: blue, red, green, yellow, or orange. If you call them direct, you can have those mixed and matched too. The sights are rock solid as well and their customer service is second to none. I just got one with 4alternatingred and blue .010 pins with their 3 stage LED light. To my door was $87 from AIIX's Archery:

Short of that, I'd look at Montana Black Gold, Copper John or Spot-Hogg
