I think (at least lately) Sonic is much more a custom builder than Fountian,Formula, or Donzi. I would be happy to have any of the four. If the Donzi is cheaper then that would be the one to pick in the donzi vs sonic question. But I wouldn't expect them to stay cheaper for long. Check out PRA mag's review of the Baja 30 Outlaw p.34: $198,600 w/525's. Dano has an '03 Sonic 31SS with 575's, custom paint and interior, and every option (I think even AC) that retailed for $197K and change. Makes the Sonic price seem reasonable. Bigger power,10+mph faster (99 on gps after dialing in), more options, higher quality.
