iSCSI initiator?

[billyprefect]

Hello. My server is up an running. ML with server.app, SMB doesn't seem to be an issue for Windows 7 machines, however it isn't working with my openElec XBMC machine at all, so I opted for NFS sharing.
What I would like is iSCSI without having to pay $90 for an initiator. Any thoughts or suggestions?
