Least expensive will be the lil P at natchez shooter's supplies, it is 149.00. It is also the smallest prismatic at this point. I have a couple of those, and they work great for what they are. Bright illumination, and lifetime warranty.
I also have several 1x Spitfire from Vortex. It is larger and heavier, bit I am a fan of the drt reticle. It is very basic, and in my opinion as close as a simple dot like a red dot has. Good illumination, and lifetime warranty.
I have an eotech xps2 sitting in it's box. It is the only optic I have that has failed on me, and they wanted to charge me to fix a known problem they had. Their warranty sucks, and I will never buy another one of their products.
I personally don't need a ranging reticle in a 1x optic, to me simple is better, and these are the ones I have experience with.
