I've found Cepheus Modern, which is based on the Cepheus Engine SRD, to be a good set of rules for modern era RPing. It's not something to consider though if presentation and artwork are a concern, as there's barely any art to speak of and it's a very nuts & bolts, one column layout. It's a considerably simplified version of the CE rules, with core careers reduced to 8 (3 more for casters in the Pyshic Powers and Urban Fantasy chapters) and the skill list pared down to less than half.
There's next to no bestiary, but it includes a robust 5 step process for generating your own animals. There's also 4 pages of alien trait descriptions in the Aliens chapter, which is for modern campaigns that will feature extraterrestrials. Other than what's stated in each skill's listing, rules coverage is limited to combat and hazards, so it's best used in tandem with the free Cepheus Engine SRD PDF.
For the couple of dollars it costs, IMO it offers good value and is a more than decent tool for supporting a modern era campaign or adventures.
