Look at a Ruger, a Llama, Detonics, EEA Witness.
You'll have 3 basic levels of firearms.
1. Junk stuff that runs $150 and is nearly worthless.
2. Midlevel units that will run from $250 - $450 and will give you good consistancy and performance. At this level the firearm will usually "out-shoot" you for several years unless you're already proficient.
3. Performance level, running $500+. Either limited production, collector's pieces, competition grade, or customized. Designed for extreme accuracy or concealability.
Get to gun shop and pick up several different brands and see how they feel and what fits your hand the best. Then combine price with what you want from the pistol (ie. target, competition, plinking, hunting, home defense, carry, or some combination).
The EEA Witness is a good mid-level start along with the Rugers. If you have the bucks, consider a Kimber or Para-Ornance. Springfields are between the Rugers and Kimber's.
There's a recent entry into the low level called a Hi-Point. Very basic and blocky along w/very cheap. Watch this one as it's kind'a picky on the ammo it likes to work with.
good luck.
