I'm planning on getting a 256mb stick of KingMax PC-150 CL2 6ns in the next few weeks (waiting for a refund on some 256mb PC-133 CL2 7.5ns 1st from another company) for ~$50.
Here's a stick of 512mb for ~$100 from

They were very prompt in returning my email ?'s explaining that the OCZ PC-150 is oc'd PC-133 & the KingMax is a true 150mhz TinyBGA ram. I'll let ya know my opinion on it after I run it for awhile. Prolly in a month or so.
Have a good one,
