Honestly, if you picked up a tong, I suspect you can easily earn a small profit from reselling, if its what it's supposed to be. Say, $250 should allow you to sell out fairly quickly.
To be entirely frank and honest, good deals in Taiwan for gushu that mom and pop operators probably didn't buy into with any fervor...
Not that it's impossible. One person doing a Taiwanese Yahoo auction shop has had XZH '06 LBZ, and it would always be a *very* reasonable price of ~$300 last time around. While that dude would be trying to sell what is probably an inferior (I haven't had it) '08 ChenShengHao for almost $850. Of course, though, the CSH is still there. Also sold a ChenGuangheTang '05 for ~$150 in Nov '13.
Now, that dude was just selling single cakes, though. Perhaps from a relatively private collection.
