I am looking at the Clevo P150 or P170 series. Apple is out as I have Pc software and they cost may too much. I have seen some of the high end Levono with 1394 but no Dell's, at least not the Alienware or XPS units.
budget is $1300-1500.
I wouldn't look at a gaming rig (like the Alienware or XPS models) for firewire. The Dell Precision series, like this one does include the capability:http://www.dell.com/us/business/p/precision-m4600/pd?oc=bwct72b&model_id=precision-m4600
Also, consider Dell's Outlet store. Great buys can be had here:http://www.dell.com/outlet
