Yes, I bought two sticks of the 256MB HyperX pc3500 at ExcaliberPC.com for $70. each last Sunday. They have sales on the weekends lately. And I got it the day after I ordered (I do live close by). ExcaliberPC's reseller ratings are a perfect 10. They are by far the best I have ordered from so far (one day faster than NewEgg). I've placed two orders and got both the next day.
People uslually do well the the TwinMoss/TwinMoss and TwinMoss/Winbond, but its not a sure thing like the HyperX. I'm running the HyperX at 200MHz fsb at Cas 2-2-2-6. I'm sure it would run a lot faster but I'm at the limit of my mb.
