Look between Curridabat (MultiPlaza Este) and Tres Rios (Terramall). You are far enough away from Downtown/UCR area for decent prices. Cartago is definitely cheaper, but further out. Check a couple of blocks to either side of Ruta Nacional 2. I like the Plaza del Sol area. Lots of transportation options. Check out the iFreses high rise, smaller units around $800

Another strategy is to look along the San Jose - Cartago train route, especially if you are sold on Cartago/Paraiso
