Genuine old tree Bingdao is not available in western outlets.
Genuine LBZ?http://www.ebay.com/itm/2008-Chen-Sheng ... 2c541e1177
well, there are some HLH...http://www.yunnansourcing.com/store/pro ... oduct=1778
not such a good price either. In fact, from what I've read, neither of these are especially great examples of LBZ.
This is not pure LBZ:http://www.houdeasianart.com/index.php? ... ts_id=1348
The price is not completely awful, and I've had it, and it's an okay representation, especially in the early brews.
Puersom, based in Korea, but who will ship internationally, offers a Hekai xiaobing that's spiked with some LBZ for $66/200g. I've heard this also works ok.
If you're agnostic on your lincangs, then I recommend that you get something like:http://www.banateacompany.com/pages/pue ... Charm.html
It costs less than any serious Bingdao, and I would wager a small amount, given how much Bingdao is a hysteria on much less quality foundation than good LBZ, that it is better.
If you're shivering over the prices, why not try some stuff from Bannacha?http://www.bannacha.com/en/mengku-jinqi ... -jiao.html
This is tea from areas close to Bingdao and is often substituted for it. It's also a reasonable 50 euros for a bing.
Another try at getting something "cheaper" would be this 2009 HLH...http://www.yunnansourcing.com/store/pro ... roduct=830
I have little faith it would be that great.
You can also try:http://www.yunnansourcing.us/store/prod ... roduct=188
Again, no promises that it would be especially great.
Rule of thumb:
You can't expect LBZ, honest and pure LBZ of any sort, of any age, to be less than about $250. You should also expect, in this day and age, that most LBZ that makes it to general markets aren't going to be that good until the mania dies down. Bingdao, it will be a hassle just to get pure Bingdao, let alone pay for it. An excellent Bingdao area is going to be about $350/proper cake or more. It might be possible to find older "good enough for guvmint work Bingdao" for an appreciable fraction less. In general, Bingdao is a classic monopolist scam, because it's small enough for effective control of who gets what, and the localities are trying to set the prices as high as possible. So don't worry about Bingdao too much. Just try a variety of lincangs until you hit an area that pleases you.
