I think you got a good deal on this pistol. Gun prices tend to be regionalized, and here in Central Texas you could expect to pay anywhere from $350 - $500+ depending on condition, box, documents, tools, etc. I normally shun the Bodyguard as I just can't get over their looks, but I wouldn't mind owning one like yours. In my opinion, one of the best and easiest trigger modifications you can make is to get a steel hammer and trigger to replace the MIM parts. I'm not trying to start a war here, but I have 2 J-frames without the IL or MIM parts and 1 J-frame with IL and MIM parts. The trigger pulls of the older J-frames are vastly better than the more modern J-frame revolver. I don't recommend the use of reduced power springs, but a good cleaning and ensuring that that the inner mechanism is free of burrs and lightly lubricated should do you well.
Best of luck and welcome to the forum,
Dave
