Mike,
You do realise the cheaper RAID cards are hardly worth the effort as they are software RAID implementations and so you are gaining none of the benefits of installing a RAID card (including performance which is lousy on the cheap cards).
I would suggest sticking with Adaptec, LSI or any of the other larger brands rather than going for something lesser known just because "it's cheaper".
After all, dodgy RAID will do nothing but test your insurance policies.
