A little vague there... You should do a bit of research on your own tbh, but we are here to help your decision. I would say buy a KM, they are pretty much one of the top manufactures in the world of Hookahs.
Link to 2 hose KM tri-metal.
There is an option to upgrade the hose on there, it is completely optional as KM hoses are nice, but not washable like the Razan. Make sure you get a second hose as well.
Also it is completely optional to upgrade the bowl, but I would suggest getting a Phunnel.
John is an amazing vendor and has great prices... you can do some research on the vendor reviews section and check out his reviews. One of the top 2 stores on here, the other doesn't have much in stock right now. He also offers 10% off purchases over $45. Call him up or send him a message on here and you will be taken care of in every way possible. Also, from what I have heard his ******* Hookah coals are pretty much the best out there.
Good luck with your purchase!
