Usual suspects 2nd hand - Xerxes or LP12 are good buys - just need to be careful of the plinth sag on the Xerxes. Not sure you will get an Orbe or Gyro for £600 including arm 2nd hand but you never know your luck.

New or ex-dem look at the project decks as mentioned, Roksan Radius 5.

Also I'd look out for Michell Tecnodec or maybe one of the new Funk decks. Good thing about the Tecnodec is if the upgrade bug bites you can always upgrade the arm/psu instead of just ditching the whole thing.

As for phonos the Graham Slee are popular, the phono from Creek, and if you are feeling plush I seen Trichord Dino go for £195 2nd hand (shadow audio have one on their website for this amount).
