Actually dude, don't buy ANYTHING until you've played a few games in different types of equipment. You can't go wrong with the BHI molle pouches, but the platform might not suit you. There are dozens of platforms, and all have their pros and cons for different scenarios.
As Stalker mentioned above, I have one of the Eagle universals. I liked it, but thought it could be improved on. So I built my own version.
This baby is has 4 rows of PALS webbing, and 20 channels. That's a TON of real estate, while staying "low profile". It has an integrated map pocket, pen channels, etc.
Of course, you probably don't have a full shop in your basement to build whatever pops into your mind
