I bought some on there last night.  I put in for a withdrawl to my Gox acct so we will see if that works. But it seems reputable.

I bought 16 GoxBTC with 7 regular BTC.   So paid about $286 each for them.

I'm fully prepared to lose that $4200 worth of BTC.  It is a calculated risk, but I think the odds are in my favor.
