Well I'm on my third week with them, and I perform at a 350 to 400 persons club, on Friday nights, I must be at that basic mixing you were talking about, I have not had any problems what so ever. I'm even loving the advance track feature when you only have that one disk with two hit songs on it and you want to play back to back. I'm not seeing any issue at all with my two decks as of yet. only effects I have time for really is the flanger and ocassional echoe other than that scratch effect sounds pretty good to me. Ps before you ask or was wondering I've been doing this since 1987 on the professional level, been though some gear, from numarks, technics, to Americandj, velocity, dcd1000 and now Radius 1000.
