Im a fairly new DJ and was wondering whether or not to upgrade from my Numark DM950 mixer to the Gemini PS676i. The Gemini has a 12 second sampler, 3 band eqs where as mine has 2, 3 channels again mine has 2 and cross fader curve and reverse. Any help?

Normally I would say, "Yes, do upgrade your mixer", but as I've seen in another post of yours, you are using belt-driven turntables.
So I would recommend you to buy at least some decent direct-drive turntables (starting from the medium price section). That way, you will have more fun with the mixing alltogether.
In my opinion, it's better to have a good pair of turntables and a crappy mixer than vice versa.

Hope that helps a bit. :)

I like what you have. You should stick with it.
