Pioneer made cheaply ? I don't think so !!!
Why do 99% of all clubs worldwide have these installed ? Because they are industry standard as are SL1200's. I have had my DJM500 for 6+ years and it's been as reliable as my 19 year old SL1200's.

The AH maybe has a better EQ if you wanna piss about on that but in the real world when your playing in clubs you really want a mixer which you know inside out. I have only ever played one club in Tel Aviv that had one and the DJ booth was very dark and I thought the layout was a little awkward and the knobs too small. I must admit I liked the filter and the smooth crossfader but i'll stick to Pioneer anyday, it does the job very well so why complicate things.
