Re: I wanna start.... but where at? *PICS*
First I'd say clean that up. Check to see if it's airtight, and check for corrosion. If it's okay, but the needed accessories and shisha from H-S, but instead of the free hookah use the hookah pro discount code.
If the stem is no good, you could buy a new KM stem. I think Hookahstore has a carnival style for between $30 and $40.
