I have and am pleased with my Primary Arms 3x compact scope.
Or, if you want to spend more for the same scope, there's the Burris ar332.
The great thing about them IMO is that they are etched reticles, so if the battery dies, they're still 3x scopes no matter.
I also had the Lucid HD7, it too is also a great scope IMO.
Hope you find something you like whichever scope you decide to get.
