DTH's glassware is very thin and feels disturbingly like plastic. I didn't like the various bits I'd bought from them (cups, gongdaobei, etc.).
I found a heavy and pleasant grey-clay funnel at YS which is pretty good. It clogs up every now and again, despite my best attempts to keep it clean, and so I now need to replace the cloth screen for some new muslin. It's a nice piece, though, and doesn't suffer from the "thin, cheap, and nasty" aesthetic that you get from thin Internet-bought glassware.
