Check out Sky Glass out of Eugene OR, they make excellent scientific pieces from Schott glass. They are currently making me a
custom "starter rig," which is very similar to the verdamper bell jar. It also (with an adapter from Elev8) is going to be somewhat similar to the famous "FC-UFO," at least in basic format.

I also have a
SPV Megaglobe, which is an outstanding deal for not a whole lot of money ($63 US for the globe, glass mouthpiece, and whip mouthpiece. It really is an outstanding deal and has and will be my daily driver until Sky ships me my new school UFO
Best piece of cheap glass I've gotten to this point (although there are some other contenders).
Let's see if I can't upload a video lol... I can't figure it out. I have a nice video of a morning draw from my SPV, but can't figure it out. Anyhow, it's super cheap and has been super reliable. Still can't wait to replace it with the Sky piece.
