I would definitely throw my hat in with the Sig Romeo 5s as the most budget but great value option. I run this on multiple carbines and is reliable. Shake awake is amazing feature. Agree with others regarding Holosuns. I also have 503R and 515GM/515CMs on other guns. I have found the Holosuns very decent and much better than the mushy-button Vortexes, for which I have gotten rid of all of them. The 515 series will be pushing your budget at 450.00 + tax, but both are great (CM has the solar backup, GM has see through glass flip covers which I never need to flip). I am running the 515CM on my semi-auto 12ga. All the Holosuns I listed are also shake awake so you never really need to turn them on or off (10 minute interval before auto shut off I believe - the Romeo 5 is only 2 minute interval).
