http://www.ebay.com/itm/301835447752Seems to be another version of popular 858/868 hot air stations. No idea what channel buttons do but my guess is you can set temperatures there for different rework situations.
I am very tempted to buy it and tear it down
Edit: Edited topic to contain actual model, only one seller on ebay,
basically it is different package for 8858
Actual cost from china : 198 yuans, (23€).

I love the fact it is labeled ESD SAFE. Wouldn't want non ESD SAFE air to blow on your boards.
No, it's not worth it. The stand is useless. The interface that can't stand up on its own is useless. You'd have to build a proper holder for it.
So found original supplier from chinese 1688 (alibaba) but it is not available on international alibaba
Edit: Well ordered regular 858D from Germany for 48€ incl. shipping
