Try some of the rosewill ones.

Be careful and select one that does the raid mode you want and has drivers for the OS you want.
Some of them have multi-link SATA ports where they have 1 or 2 physical ports, but you can plug
5 multi-link compatible drives or less into one physical port, but to connect 1-5 normal drives you'll need
a multi link SATA expander cable / device. Those aren't all that expensive at some other e-tailers, though they're not as easy to find or cheap as I'd prefer. They're a nice option if you're going to buy an external multiple drive enclosure anyway, though, which are available with integrated / integrable multi-link to single-link interfaces.
Of course some of their other cards have multiple single link ports, though.
The LSI SAS3442 is sometimes available around $130, and is commended for a relatively cheap multi-port SAS controller. SAS is backward compatible with SATA, so you can plug SATA drives into it.

Manufacturing companies like SIIG and ADDONICS typically have several inexpensive PCIE RAID
cards in several models, and they're commonly sold by various commodity priced etailers.
PROMISE has various ones too.
I'd go with the Rosewill or SIIG/ADDONICS for low cost typically, and maybe the LSI for higher end applicaitons.
