I was in the same boat you are in now about two years ago.
Keltec .380 is called Kel-tec P3AT. Ruger makes a spitten image called LCP. There is currently a recall on the LCP as supposedly it (MIGHT) go off if dropped. I own one and am very pleased with it. Kahr Arms is coming out with a P380 this month. Kahr is a bit pricey but I believe the asthetics of the Kahr are better than Ruger and Kel-tec. However that IMO and I own a Kahr PM9.
Pocket 9's, as they are refered to, are another way to go. Beretta makes PX4SC, Beretta Cougar, Springfield Armory XD9sc, Kahr MK9 or PM9, etc. just to name a few. They are larger than the Kel-tec and Ruger but are 9's versus' .380.
The best advice I could suggest is if you have a pistol range available see if you can rent as many as possible and shoot as many as possible. You will find one that you really like. Then start asking questions on HGF about it.
If you are like me. You will purchase one then decide you like another better then buy that one also. In two years, I have ended up with 7 hand guns. All have a different purpose but are fun to shoot.
