The models (previous models and current models)
PSR S 970/770 and now the PSR S975/775.

I mention the previous models perhaps because some people have trade their 770/970 for the 775/975 and perhaps can buy them for less.

This models will be able to store at least 4 or 5 packs (770) and even more on the 970 or 975, I have about 8 packs installed.

Here my list: 1 Banda Mexicana, 2 Mariachi-Norteño/TexMex, 3 Cumbia Latina y mas, 4 Mexico (Made by the Yamaha de México), 5 Salsa and now the 6 Fiesta Caliente....
besides I also included 7 "Colores de Iberia V2", the 8 "Latin Audio styles" (Genos/T5), and added the 9 "Russian Classical"...all those in a PSR S970.
