SATA chipset recomendations

I want to setup a Linux software RAID 1 / Mirror array in the 2.6 kernel.  I 
am looking for feedback regarding the best supported SATA chipsets.  Do any 
of these cards stick out as having better driver support?  Can you reccommend 
another card I have not mentioned?

(I am not wanting to spend the big bucks on hardware RAID, so I am not much 
interested the expensive 3Ware or Adaptec cards)

Promise SATA150 TX4 ~ $65
(I don't really need 4 ports, but, I would not mind having them for future 
use)

Highpoint Rocket 1520 ~ $35

Silicon Image Based Chipsets:
SIIG SC-SAT212 ~ $40
LSI MegaRAID SATA 150-2 ~ $35
Buslink PCI-2S ~ $30
Koutech PSA150 ~ $25
Kingwin SAC-02 ~ $20

I thank you for your time,
