It's already been said that you won't get any profit from these (nor, let's be honest, from pretty much any other miner) and buying one is pretty much ill-advised. However, if you absolutely want to have one: contact asicrunner.com - they appear to have some back in stock (status changed a day or so ago). They're also pretty much the only place to get one outside of the odd BCT marketplace or auction/personals site listing (there were a few up on craigslist AU, seems gone now though).
