SDRAM recommendation

[Cosmic Cruizer]

I need to buy a new SDRAM module that is comparable with the HP 512-MB
SDRAM, non-ECC PC133 memory module P5090A. What would be the manufacture and
part number of a low-price alternative?

Then again, if someone has three of them they would like to trade, I have
(2) new Compaq 1-GB ECC PC133 SDRAM and (2) new Compaq 512-MB ECC PC133
SDRAM for a straigh-across swap.
