I don't usually hang around in this section but if by cheap you mean US$50-US$130, then you may want to consider the old Dell PERC 5i or PERC 6i. They're both LSI cards, the 5i can do RAID 5, the 6i can do RAID 6, my 5i seems perfectly happy being managed through the LSI MegaRAID Storage Manager application, and both the 5i and 6i support up to 8 drives. One of their major drawbacks, however, is that neither of these cards support physical drives larger than 2TB.

Someone else could probably chime in with better suggestions.
