Well I thought I'd best post a follow up to what I decided on in the end. I got myself some Pioneer HDJ-1000's even though noone has raved about them here, which is surprising actually as they are excellent, although I certainly wouldn't recommend them for reference listening as they are far too harsh in mid range.

Just try not to buy fakes, if you think you are getting them really cheap, then they are probably fake,

Pros:
Very f***ing loud
The foam cups block out allot of background noise
Solid build
Cons:
Very f***ing loud, and if you have sensitive hearing they will hurt, so keep them to a minimum!
Swivel heads aren't as free as the Sony design, although they are solid.
Not good for reference listening as they do not produce a flat response.
Expensive
