I can't particularly recommend Sandy Bridge at the minute considering the problem there is with the chips.
Certainly reasonable, particularly with a need for multiple sata hard drives.
Some e-tailers have withdrawn P67 motherboards, which will probably cause prices to go up because of shortage. The sandy cpu's also.
That said, the two 6gb sata ports of the P67 chipset are still good, and some motherboards have added marvell ports. Add-in pci-e sata cards are also available.
So, until this gets sorted out, current P67 users should mostly be in good shape. Down the road, one must be prepared to replace the motherboard with a fully functional one.
The motherboards typically have a 3 year warranty.
