coreupt is legit and super cheap if you can find some from last year!
i got a brand new pair of coreupt tj schillers for just 99$ :)
so far they hold up very well, i've got them centermounted and my first impression of the ski is that it has excellent edgehold on groomers, skis very easy in switch, has a ton of pop, is medium to stiff and has great stability at speed, i have it in 183cm (i myself am 181cm tall) and it skis quite short because they have very big tips and tails which gives the ski an actual running surface that is shorter than that on my 176cm movement joysticks ...
I'd suggest the ski to people who like to go fast, rip on groomers and stomp bigger jumps, the ski is very playful but if you're looking for a soft noodle jibbing ski, this isn't going to be your thing ...

a small side-note about coreupt, their skis from 2009 and earlier were rebranded dynastars and had terrible durability issues which gave the company a bad name, from 2010 onwards they produced their skis in their own factory in china and remarkably their quality has improved !
