I have ssj Vegeta, I paid a lot for it, and the fact that I did makes it so that I'll probably never sell it, because if I didn't want it this badly I wouldn't have paid this much in the first place.
Nevertheless, I rarely try to make profit on stuff (granted I never needed to thus far). So my aim is always to try and sell without loss. Honestly doesn't really matter to me who I'd sell it to, I'd just wanna try to minimise my losses if possible to zero. Didn't get into this for profit and I don't think I'll ever will.
