Seems like a good scope for the money - Viridian OpticsPlanet Exclusive Serac 2-10x40mm Rifle Scope 30mm Tube SFP

Provided you get this scope in the low $100 range I think it's hard to beat for the price. It's illuminated (the dot gets nice and bright), has ample eye relief, and the view is clear. Note that it didn't come with a battery (2032 size). It did come with cheap bungee corded scope caps. I haven't owned this long and it may not turn out to be durable in the long run but first impressions are promising.
