If you can find a legit eBay user, they are fine. I bought a Intel Pentium 4 3.4GHz Extreme Edition for my old 478 system in 2005 for $150 and it still is running great. So I have had it 5 years and it has yet to die and even though I had a Pentium 4 3.2GHz, this thing cut my DVD ripping times from 30 minutes to 7 minutes, which back then was insane. Might have been the L3 cache they had on the P4 EEs......
