I picked up my modem and installed it in just a couple of minutes. It was easy. When I log on, it seems to connect at 49333 every time. I guess that is good because my 33.6 connected at 31.9. I was going to buy that $25 one with the $20. rebate but from the reviews - you get what you pay for. I  went with Diamond and I am glad I did. The box says the requirements are  for a pentium 133 or higher. I have a Pentium 120 and it has worked great.
