Reply to Dj tech kontrol one??

hey guys.. have the oppurtunity to pick up two kontrol ones in a road case that will fit a 2ch mixer in between for $250 are they worth it?
has anyone had any experience?
i can map well in traktor been doing it for over a year and they look like a dream for me, plus the metal construction is a bonus,
if anyone can help out id really appreciate it!
