If you are around the 250MHz or lowewr the HX series I linked to will perform alot better due to the tighter timmings and lower voltages. The HZ is said to be quite sloppy below 250MHz. If you wish you can check out a review of the HZ series..here.
There is also the ZX series in 2 x 1024Mb modules..here..for US $195.00 but it is not up to the performance of the HX series.
