DO NOT GET A 2003 Powerstroke!!! That was the first year for the 6.0L and they had HELLA problems. Hell, any year of 6.0L was chit. I would go with a 7.3L Powerstroke (99-02) if you have to go with a Ford diesel. If you want a diesel, go with a Cummins 24valve (99-02)---or get the HO Cummins (01-03), available with the NV-5600 (6-speed) tranny. Or get a Duramax...and year motor is good.
