That's a good list to work from.
I have one of these on my AR rifle:
Leatherwood Hi-Lux CMR Rifle Scope 30mm Tube 1-4x 24mm Illuminated
It has all the features you're looking for, including price. I think there are better scopes out there, but not at this price.
The maximum magnification is 4x and that's plenty out to 100 yards. It's OK at 200 and not as much as I'd like at 300. Compromises must be made though. If you're going to use it at a 3 gun match, you'll want the 1x as well.
A 3-9x40 would be better for the long ranges, but will leave you wanting a larger field of view at close range.
