I don't own one, but I've thought about it. The online consensus is that the Bersa is a nice little blowback .380. Despite it's low price it has a good reputation for reliability and is pretty accurate. It is aluminum framed, so there is some concern about longevity, but it seems to hold up for at least several thousand rounds. Like Sprat said, it will never be worth lots of money. While holsters are more available than they used to be, even good spare magazines or new grips can be tough to come by.
It is competitive with similar guns of it's design type like the Sig 232 or the PPK/S. The sig is probably a better made gun, but it also costs over twice as much. The PPK/S isn't a better gun. Not only does the Bersa cost significantly less, but it has a better trigger, is more reliable, and doesn't slide bite like Walthers (or the sig for that matter).
The problems? Well it is a blowback so its kind of big and heavy for something that slings a .380 round. Kahr and Keltec both make guns of similar size that shoot 9mm (or shoot the same round but are smaller). But they cost more and are generally harder to shoot well. The bersa isn't big in absolute terms, but you probably want a holster not a pocket.
