The most prominant ones I'd look at in a 1-4(ish) range in no particular order:
Leopould Mark 4 MR/T 1.5-5x20 M2
Nightforce NXS 1-4x24
Vortex Razor HD 1-4x24
US Optics SR-6
Although I wholeheartedly agree with your list, all of them are WAY over the OP's budget for this scope, even on the used market.
