Cheap (~$150 or less) dress pants in London?

[FidelCashflow]

I'm in London for 2 days this month and am looking to pick up some cheapish staple dress pants in a modern fit. Suggestions? I've tried TM Lewin before with good luck - but am not sure if there are better options out there.

Roderick Charles and House of Hanover both have decent selections in your price range. Also worth checking out the Charing Cross and Bank branches of TK Maxx, they usually have PRL and RLBL trousers for $100 or less.
