There is a China made Eotech 551 that is Holographic but they cost $210 shipped. The ones that are not holographic run about $80. You can buy a Bushnell Holographic sight for a little more that comes with a warranty.
The China made AP copies are a steal for what they cost and the performance you get from them. They are very well made for the money.
