It is a Zhongdi
http://www.china-zhongdi.com/zd-917.htmZhongdi soldering stations are pretty common among hobbyists in Europe and are good enough for hobby work. I won't trust them in heavy 24/7 usage in an industrial shop. It is not high-end stuff, but has made its way into the offerings of large electronics retailers (rebadged, of course).
You get them, and - important - spare parts in many online shops and on eBay.
Especially regarding the ZD-917, the desoldering gun is known not to be the most robust. A spare is about 15€. If you don't absolutely need desoldering, consider a soldering station like the ZD-936 or ZD-937. And the 147.40€ that Greek shop is asking for it is way out of line. 99.99€ like here
