Think you can add Infineon to that list, as Mushkin now is using Infineon 7ns chips and are guaranteed to run @ 150Mhz 2-2-2.
The Infineon modules are a lot cheaper (~$40 for 256Mb, bout half the price of Mushkin modules), but make sure they have the 7ns chips. (product codes are: HYS 64V32220GU-7-C2 and HYS 72V32220GU-7-C2).
OK they wont guarantee that they will run @ 150Mhz 2-2-2, but they do come with a 10 year warranty.
