I travelled last December to Saint Martin with the new Dominican airline, PAWA Dominicana. The service was pretty good. The flight was punctual, cabin crew was kind and served a pretty good snack - some chips and the drink that you wanted. On the return flight was the same treatment but there was a 2 hours delay because of the traffic over SXM and SJU but the service was the same with nice treatment. They have some old airplanes but in a good condition - the interior of the MD80 was shiny and clean. They also have DC-9-32 but I haven't flown that.
