Deae Putneypj,
I think at the end all will depend on your budget but if you looking to a unit to be resell easily I think I would go for El Andalous as distant dreamer said, Palm BEach Piazza which have resale units already as buyers from year ago have 100% profit , also Ocean Breeze, but if your budget is limited go for Paradise Garden its located direct behind the main road between the projects for Sahl and you cross the road to go to the public beach, but you are surrounded with Golf Courses.
May be you should come and see it your self, I think in sahl they organize free tours for projects so one day of your holiday if you come will save you alot
Regards
George
