You can now buy a 5 port SATA Card for your mac at Syncraid

You can also get a PCI cover that allows the kit to connect to external boxes without jurry rigging a pci slot with a bunch of cables sticking out of it.

BTW, Firmtek will soon be shipping it's external version of the Seritek 1s2 card.

Sata is definately going to go far for cheap. The speeds on the PC escalade cards are 400mb/s. Once mac catches up, there will be some fast Catalyst systems out there for a low cost.
