I've seen them on some shooting supply sites for $399.00 but I think the MAP price is around $450.00.

The Z-Point is totally parallax free. Dot size is about 2.5 MOA which is ideal for 50 yards or less for deer sized targets. Killer features on this sight are the infinitely adjustable red dot intensity. If you can see a deer with both eyes open in almost dark situations, the Z-Point's red dot will not over shadow the target unlike rheostat controlled red dot and holo sights where the lowest intensity setting is still too bright. The Z-Point is solar powered and uses a 2032 backup battery. I have one that still has the same battery in it after 24 months of use. It automatically goes to battery power when the sun goes down and shuts itself off automaticallyafter 4 hours continous operation to prevent killing the backup battery should you forget to turn it off after the hunt. One of the neatest fetures IMO is that the Z-Point will lower and birghten the dot intensity automatically after you set the brightness to your choosing. When it starts getting dark the red dot intensity will start dimming automatically so you don't have to go back and do it manually. It does the revese of that in the morning as the sun comes up. It will slowly brighten the red dot automatically. It's water-proof and the optics are second to none. Just pick one up and compare it with any crossbow sights or scopes in very low light conditions in thick cover :-) Yes, I'm sold on it :-)
