Yes, I think he means the E or Exquisite, dollar-a-gram stuff, which is amazing, but obviously too costly to do more than taste once per lifetime. He reviewed it in his blog
a couple months ago.
That's roughly $400/lb, right? That's somewhat expensive, but not anywhere near unheard of in the world of tea (and, if you figure 6-10g each time, with probably a good 8-20 infusions, it's not that insane an amount of money to spend). I don't think I've tried that particular tea, so I can't speak to its quality, but given that it's such a prestige tea, it's hard to find high grade, hand processed DHP for cheap (though, of course, if you pay a lot of money for the tea, it still may not be good).
I /might/ have tried this once, with the LA tea group, and if it's the one I'm thinking about, I didn't get my socks knocked off or anything (neither did most of the other folks at the table). I'm pretty sure it was from teacuppa and a red box w/ two small packages inside.
I do like the one (a 2006 or 2007 hand crafted one, supposedly from the scenic area) that Guang / Hou De had, though I think the sample I had from him was slightly better than the second batch he got, from which I ordered. He doesn't have it any more. I've heard good things about the Rou Gui from the same factory too.
I have a medium roast one from my trip to Wuyishan that I think is pretty good for the price (roughly 60 US for 1 jin (500g)). It's not a traditional roast, but not super green either, and has a nice little spicy flavor.
Yan cha is tricky to brew IMO, and I think it takes a while to learn how to appreciate it too. I don't claim to be good at either thing, but I'm definitely hooked anyway.
