A cheap, mostly plastic, Daisy 880 from Walmart will easily meet your criteria except the adjustable two pound trigger. Put a $40 scope on it and you should be able to hold under one inch groups at 25 yards with Crosman 7.9 cardboard box domed pellets.
Maybe check out the Seneca Dragonfly?
I've never owned a Benjamin 307 but they have a loyal following.
If you consider going the CO2 route, an Umarex Fusion or QB78 are good options.
