why not go with the 3ware 7000 series cards ? I haven't heard much about their RAID stuff, but Tekram has pretty good low-end scsi controller stuff, budget kind .. 3ware seems to be the defacto standard for ide raid .. just my thoughts .. if you just want 2 channel RAID0 the 7210 can be had at hypermicro.com for $135 (don't forget to mention Storagereview.com in the order for free shipping)
