There are plenty of options out there for you for under $90. I would suggest checking out some of the dealers on here, you will find fantastic deals from many of them.
I would suggest checking out a Magdy Zaidan or Khalil Mamoon as you can find a 32" MZ or a 34" KM for around the $90 you want to spend. I saw a special Hookah John is running recently for about $100 it includes a 32" MZ, 4 50g packs of AF and some of Johns coals.

End result will be up to your personal preference but always take some time and do some research, and ALWAYS ask questions on here when you are unsure. Good luck and happy findings on your new hookah, let us know how you like whatever you decide on getting and maybe even do up a review.
