If you're looking to spend less than $200, go for the Mushkin Siemen Infineon PC133 stick. It's $165 at the moment I believe. However the "REV2" Mosel Vitelic is the $195 128Meg stick, and I think it goes somewhere around 155Mhz at CAS2. So it depends on how much you're willing to spend 🙂 The packaging Mushkin uses will make you smile.
