Can anybody recommend a dunlop squash racquet (racket) for an intermediate/advanced player?

I have found that lilliwhites in London sell dunlop equipment very cheaply because the owner (Mike Ashley) is also the owner of dunlop/slazenger/umbro/karrimor (the list goes on). If anybody could recommend one or two racquets I would be very grateful.|||A NEW ONE|||Can't friends at your club help, surely they can advise?
