So a friend of mine is buying me a late b-day present in the form of any smoking piece i desire within about a 30 dollar budget.
Now i know that doesn't sound like much to work with when buying a pipe or bong, but ive found some killer deals at the local smoke shop.

Only problem is i have no clue what to buy, i know all the pros and cons of pipes and bongs and glass and acrylic and what not.
I have a small pretty cool pipe already and a foot 1/2 acrylic bong (which has been at a friends for going on a 6 months now ahah).

I have pretty much decided on buying a bong, though i cant decide if i should go for a glass or what.
I love either kind and unless its just tiny the size really doesn't bother me.

I am guessing my price range would get me either a big acrylic or maybe a foot or a little taller glass.
If i did get a pipe, i could maybe get a 4 or 5 inch long not too fancy one.

So my question is merely your guys preferences.
Basically i want you guys to decide for me.
