I can second the Bersa Thunder. I do not own one, but have shot a few and know someone who owns one. A good value.
Another good option is the FEG PA-63. PPK copy, alloy frame for light weight. Available in 9X18 and .380 auto. Cost is just over $100. Several ads in the current Shotgun News for them. I own the all-steel cousin, the FEG-APK MKII and really enjoy that pistol. If I could do it over again I'd get the PA-63 for the lighter weight.
