You can get a Burris Fastfire III or a Vortex Sparc 2 for about $200 and both have a lifetime warranty. They both are very light and compact. The Aimpoint is a lot pricier and I honestly don't know if it's worth the money. The weak spot for all the compact sights may be the single mounting point. The tube-type that use two 30mm rings look more rugged to me. I also like sights that use 2032 batteries as they are cheap and easy to find. Another thread a while back had some complaints about Aimpoint's actual battery life and the oddball battery type.
