Surely there's at least one, somewhere out there on sale? If not check out ebay & amazon, Ti4200 is (or at least was) one of the most common models to be seen. Except for maybe "MX" series, which is a whole other story.
I do have a MSI-branded GeForce4 4800SE, which is a very rare model indeed. Never saw (or got to pick up) another one ... it was actually given to me for free from a guy on another (local) forum here in Croatia. According to him, it's been used for professional purpose at some point & then put away into a desk drawer for years, or rather decades.
In fact, I even had 4800SE mounted inside the Visualize Workstation, for several days before the system hanged up with black screen & stopped responding entirely. Which I don't believe it was due to AGP card, as 4800SE is still working today inside another (Athlon XP, Socket A) system.
