I really apologize,
my recommendation was incorrect.
The current U.S. Robotics PCI Performance Pro is Model# 3CP5610A
I just got one for $70 from buycomp.com
I have been using USR modems for some time now, having purchased 3 ISA Hardware modems and 3 PCI modems now. However, though the PCI model installs very easy in Windows 98, in NT it was a nightmare. Do NOT buy the USR PCI modem is you run Windows NT. Even though it says it is "controller based" and implies it is hardware, and says specifically that it supports Windows NT, it is a 50/50 shot, and calling tech support when their driver doesn't install via the default installer resulted in a conversation which revealed that they know little or nothing about how their install works in Windows NT. They didn't know what APIC was, how to have any control over which IRQ their modem installs on (in the bios, via software, etc.), and were totally unable to help. I went back to the US Robotics ISA modems, and they work great.
So I appologize for believing that a good company would always produce good products, and recommending somthing before I had tried it in all situations.
