Sheldon Black Beaker Bottom!?!

I Am thinking of getting one of these locally, the Real Deal for like $375!!! It is just a (i think) 24" Beaker bottom, Thick Glass, Pearl Diffuser and Ice Catcher. i Just want something Simple and Classic like my old Roor and the guy said that Sheldon Black is Actually the Old Roor Guys they just changed names because of the knock offs... Is this going to be worth the purchase?!

or ... http://sheldonblack.myshopify.com/collections/beakers/products/13-grasso-beaker-38mm-f19
or even better... http://sheldonblack.myshopify.com/collections/beakers/products/16-medio-beaker

What is the difference in Grasso and Medio? i Think i like the 16" Medio the best honestly and i can buy it for $222!!!

My buddy has nearly the exact piece/type of piece you are thinking of. It works great as a stock bong, but when you start adding ash catchers and things like that it gets really really unstable. His regular rig with his attachments to make his ash catcher work make his piece look like optimus prime

Great simple bong

Seemingly unstable/risky to get attachments for.

I also feel like his stem is a pain in two asses to clean, at least from my memory
