If you want to stick with Hikvision, I recommend you look at milkisbad's offerings here: http://www.ipcamtalk.com/showthread.php/257-Good-source-to-buy-IP-items-at
His prices are very reasonable considering they ship from the USA and you get a nice warranty and you don't have to deal with questionable aliexpress sellers. He has 4MP cameras too.
Also important, whatever you get from milkisbad will be English versions, not Chinese versions, so they won't be compatible with Chinese Hikvision NVRs.
NOTE: They will work with a Chinese NVR if you have loaded a flag changed firmware or you still running a old version firmware like 3.07 or 3.08 as they support both regional cameras.
