Maybe AKG K518 DJs(£38)? But they are said to have a 'good' bass so if you're not wanting bass then maybe not.
The Senn PX100 that you had are generally thought of as one of the best in that budget and said to have a good solid bass.
I have the Senn PX200 as I didn't do my research properly

and thought they would be just like PX100 but closed. They are not overwhelmingly anything to my ears and they are certainly bass light. I suppose I would say stay away as they are fairly universally hated by those in the know.
