Review on High-Point RocketRAID 3742A 8 Internal, 8 External Channels 12GB/S PCIe 3.0 X8 SAS/SATA RAID Controller by Lamar Hopkins

Reasonable price if you use SATA drives. Don't try to use SAS drives unless you're using their overpriced rack mount case. I am using a Norco RPC-4220 and the controller failed to recognize 2 different SAS drives that are on Highpoint's compatibility list. Highpoint Support replied to my ticket that the backplane I'm using may not be compatible with their controller. When I asked for a list of compatible backplanes he said they don't have a list and their cases have backplanes that they know are compatible with their cases. So be careful, if you want to spend money setting up SAS with anything other than their cases, you'll end up going with SATA 6Gb/s drives instead of 12Gb/s SAS.
