I really like Cobra sights. Super bright, less than $100, and Made in USA. Their customer service is also top notch. I broke a pin and a fiber optic a couple years ago. I can't remember if I called them or emailed them, but they had replacement parts in the mail within a couple days. I'm currently shooting the Boomslang Plus 6 with the 0.19 pins. I've got a 4 pin model laying around somewhere with 0.29 pins. If you're interested in it, let me know.
