The only other intact tabletop siphon I have for comparison is the 5 cup Yama, it looks a little thicker, but it may just be the smaller globe. I think the hario's have the best bottom glass, but replacements are tough to find at a reasonable price shipped, so my 3 tasse hario stand with broken bottom globe and missing top remains a project.
I prefer the yami stand, but the double ring gasket on the yama seals up a little better/easier. My yama stand likes to lean a little.
Lately I have also tried using the 3 tasse Yami glass with the 5 tasse yama stand, just to get a little clearance on the butane burner. It seems to work a little better with some room, the stock yami is right on top of it.
Maybe I should build a frankensiphon, a hario or yami stand, super thick hario bottom, inexpensive yama top with the nice seal.
By the way, if you are going to buy 4 at a time, you can get them from Amazon just under $40 ea shipped for the 3 tasse tabletops with the 3 for 4 deal.
