Which SAN box to buy for Clustering?

Hi,

I have a number of physical Windows Server 2008 machines at home and want to
create a cluster environemt (Win 2k8 - I administer Win 2k3 at work) -
however, I also want to learn a bit about SAN - so, a bit of a dumb question
but can anyway recommend a cheapy (sub £1000) SAN box that I can setup and
configure at home and learn Win2k8 clustering?

Thanks,
lara
