as said up above, a QT, Bambino, a mini mya, they'd all be your best bet. and relativley inexpensive. use Nats!!!
I use exoticas over coco's. I think they burn easier and if you can manage the ash they give some of the best evenness of cook. I also have 2 nammor hoses which I would definetly recommend. as ride said, hookah-shisha.com is the only vendor that has official nammors. the rest will be fake.
