hi there. it’s real easy to get to wukuaishi these days: metro to the north train station and any rickshaw/motorized whatever to the market. This is really the only choice for good, reasonably priced tea. There is a good puer shop in Xiao Jia He, right by the Lhasa Hotel, down the street from the Roman Plaza or whatever its called. Right off of first ring. But they get their tea from wukuaishi.
There is no good alternative. suck it up, take the metro, get on a rickshaw, browse the market, spend cash, go home and grin.
