It would also be great if people posted links to the glass if still available to purchase. I see dhgate glass always mentioned around here but can rarely find the pieces discussed.
that I love for flower. But yes, for low temp dabbing even the Chinese FC-710 beats the real deal Mobius for concentrates IMHO. The ball acts as a valve letting fresh, cooler water from the bottom of the bong into the tube. So the actual water in the tube is constantly being changed and cooled. The water volume of this piece is huge but the actual contact the vapor has with the water is actually less than any other perc thus saving the flavor of your dab. Hell, for under $40 don't worry about the science behind it, just buy one and try it out. You can sell it to someone here for $5 under cost if you don't like it, but you will. Honestly that's the price of a gram of the best and that doesn't last me very long!!
Cheers all! 
My favorite glass ever is oddly enough some of the cheapest I have owned.
To choose "favorite ever," I decided to pick the piece of glass that I would miss the most if I ever broke it.
For me it is the FC UFO, a simple showerhead bubbler with a large can and modular MP.
I am using a very tall mouthpiece from VXL.
Recently I have had to stop using flower daily, because quite simply it gets me way too high, for way too long. It sounds counterintuitive, but concentrates are way more adaptable to my productivity, and I'm currently juggling a job with an entertainment company (EVERYONE in Hollywood smokes which is cool) and school at the same time, so I just dab in the late afternoon and save flower as a weekend treat.
The FC UFO has a beautifully cut showerhead perc, and even though it is very low diffusion I have grown to love the maximal flavor from using it. I abhor honeycombs and fritted disks.
I like using the long mouthpiece because
A. It looks more civilized (although I like the big mouthpieces!)
B. It cools the vapor, somewhat in the same way a whip does.
If you are thinking about a new piece that isn't Chinese but isn't exorbitant, @Justpassedu , I would REALLY look into Apix Design. American made and really awesome stuff. Probably a level below Sov aesthetically but the function is just about as good and the guy Dan, who runs the company, is real nice.
His site is Apixdesign.com but it's down right now as he is on vacation.
My favorite glass piece is the Mimi piece from elevate Jane. It's a sexy little waterpipe that has a vortex perculator. I e tried inserting an image but it doesn't seem to be working, sorry!I been collecting since my early high school days . As i got older , moved , different things came up in life . I had to sell it all through out the years. Looking back i loved all my Jerome Baker bongs , i had a few of those and some Roor piece's back when they 1st started. I would have to say my absolute favorite that i miss the most is the Hurricane i had . I believe they were made in Germany with almost indestructible glass , double water filtration system and it had tiny holes in the glass making my smoke now would be vapor turn into a beautiful tornado on it's way up to my lips. Looked something like this :
So i am wondering what was your favorite glass piece ? Pics always help ...
Nice , I now have a new favorite the Mobius. Very Smooth , perfect size for my needs and great with Vapor or a Dab :
