To the op I would suggest you figure out who you are going to be training with and ask their opinion. Generally instructors have a personal opinion and are more familiar with one system over the others. This could be for any number of reasons with some being they are sponsored by a certain company, are involved with the product or like the Hollis rigs have a bigger margin than many other brands so they push that even though there are much better options. One rig will never suit all your needs if you are going to travel and dive in multiple environments. My advice would be to buy used if money is a concern.
