Personally I would make a road trip, about 12 hrs. each way from SFO. The cost of motor freight is crazy today. If you don't have a truck, U-Haul trailers are cheap. Also U-Haul wants to move vehicles back to Cal, so you might find a great deal on a one way truck rental, especially if you negotiate with them a bit. Grab a South West flight from SJ to Phoenix, about $95 + junk fees.
I would ship it with the stand separate.
