HECK YES!!! Been a hookah smoker for a long time now. Actually I ran a small mobile hookah lounge with a friend for a short while, it was loads of fun.
At the moment, I've got (I think) 7 Mya hookahs. My favorite is my green 21" Montopolis, I've had it for ages. I've also got a 30" Mya Obelisk as well as loads of acrylics and some others that I just can't remember the names of anymore. I also plan on buying a Khalil Mamoon hookah pretty soon.
As far as shisha goes, I've always been a big fan of Starbuzz, Social Smoke, and Fantasia (even though its not too popular with most people). I'm really into fruity flavors, my favorite is Fantasia's Raspberry Lemonade but I've probably tried just about every flavor by now.
For coals, its all about the natural coals. I actually also use 3 Coco Naras!
Lets see, what else...Oh I also pretty much solely use Nammor hoses because they're really wide in diameter and really easy to clean.
