These are the products with the current best price/performance ratio:

Assuming you are not building 1U boxes, get one of the full height
cards and order it with the maximum size buffer you can afford.
The cards take 1 SODIMM, so that will be a max of 1GB or 2GB
depending on whether 2GB SODIMMs are available to you yet.

some of you have had experiences with these, and if this cards belong to  
the "slower than no RAID" camp, like some DELL card we often see mentioned  
here, or to the "decent performance for the price" camp. It is to run on a  

        Thanks in advance for your time and information.
