You shouldn't have to travel far to find a Sabine to ride in. I don't personally know anyone who runs one down here in the lower laguna, but they sure are popular your way and north. What others are you looking at? When I think side console I think Whipray, some East Capes, Ankonas?
This fellow stopped by to help me with a sea deck project last week and he was towing this Sabine to fish the weekend. Very nice... would be tight for me and probably not enough boat to fish out of Port Mansfield regularly, but very cool micro.
