Hi, I'm a proud owner of PAM005. As I understand, PAM000 & PAM005 are kinda popular for entry level with basic design + the OP logo. That is my personal preference for Marina. For Radiomir, I will go for PAM292 which in full ceramic, and if you want to look more muscular, go for Submersible PAM024/025 for basic model (actually any of Submersible models will make me drooling.. especially with the price)
As for xxxx in Sunway Giza. Dealt few times there, it is a recommended as well as reputable shop. Hope my 2 cents help
