Certainly you'll get many valid answers here, and most based on personal choices and experience.
For you, I suggest new, and DeWalt is a bargain for any DIY with limited budget and use of the tool. Beyond that they are well suited to last as long as you might need, and offer multiple types of warantees as well as service centers nationwide.
I suggest that SKIL, Craftsman, Ryobi, Rigid, and some others are likely OK for your use.
I own many types and brand names, and use them hard in my work, but many are expensive, and consider, as you mention, "Features" You're already ahead of the game by finding a tool that has "a horn a spotlight a radio, etc", attached.
Certainly one answer suggests a great brand, and in conjunction with a pawn shop, but power tools really can be purchased at "bargain" prices NEW.
