I ordered a Grav Stax kit they were selling on here a while back, probably a couple of years ago. It included this base, a couple of percolators, an Upline ash catcher, and a few flower bowls, along with a bunch of other free stuff for around $300, if I remember right. I just looked and didn't see the same thing for sale any more. I really like this base, because I can take off the perc's and ash catcher, and just use it as a dab rig. I love the versatility of being able to add percolators, and the piece overall is really nice!
