Have a handful of samples and two bricks thus far.
My tastes run towards lighter, 'fruity' cider-like shengs rather than musky, 'mushroomy' ones.
I rather like the inexpensive 2008 Bulang Arbor brick (no longer available at puerhShop) and the Yi Wu Yeh Cha of Chen Guang-Ho Tang at Hou de, which at about $50/357g beeng, is a bit steep for me. I find puerhShop's dirt-cheap 2007 Xiaguan Tibetan flame brick okay, but not something I think I'd purchase again.
By modestly priced, I mean about 10¢/g (so it costs less than 75¢ to load up a 3-4 oz. yi-xing).
P.S. - Tony, Goose - how're your blades?
