Hey

this is kind of an alternative to bluestacks but you need to have a android,Iphone/iOS or blackberry phone for this to work, also this doesn't use a lot of cpu power on your computer at all

Teamviewer is a Remote control app that may require root on some devices, and may not work at all on some devices, NOT a emulator, so it is not a alternative

alternatives for Android Emulators would be Bluestacks or Genymotion (i use free genymotion with ARM gApps flashed)

alternatives for Remote Desktop Control would be TeamViewer, WebKey, MirrorOp (i used WebKey before, requires root)

+1 to GenyMotion. Free and fast.
