Sony MDR-7509P (In canada things are a little more expensive so I paid $151 after tax but even for that price their amazing)
In the USA they go for between $100-$130, they in my opinion out perform the Shure SRH840.
Apex HP96 ($74.95 CAN before tax)
Sounds EXACTLY like the pioneer HDJ-1500 for half the price. They felt a little loose on my head though and I`m not sure if they`d last long.
