Software!

I'm in need of good reliable DJ software (Preferably for professional Dj's) which has got the same qualities as real turntables. Defining quality, I'd like to have software with the following capabilities:

# Auto mixing
# Waveform display for indicating playing position and cue/loop points
# BPM synchronisation and beat synchronisation
# Eight effects including Delay, Echo, Auto Pan, Trans, Filter, Flanger, Reverb and Pitch Shifter
# Fader start function for controlling the playback of two players (channel, fader and cross fader)
# Create function for setting four points for cues or loops in a track

My budget goes up to 500 euro's
Thanks
