Reply to CDJ-850 or -1000 mk3 and/or DJM-400 or -350

Hi guys,

I am looking for a pair of CDJ-850 or -1000 mk3. I am also open for CDJ-900 depending on the price.
Also looking for a DJM-350 or -400. Also possible DJM-800 depending on the price.

I would preferably take an used gear in good state.
And in the UK in preference but may also get it from Europe. Worldwide also possible depending on the price.

Thank you very much!
