I bought an ex utilities H14 winch, bumper, hydraulic pto, spool valves, morse lever, tank, extra hydraulics take off etc etc for £400 ...
I have seen them on ebay since too. Sometimes the Defender Centre in stourbridge have them for sale. They sell ex utilities 110's and sometimes remove the winch set ups.
Only draw back with fitting the above to a td5 is you need to relocate the ECU to mount the tank there. Not a massive job but a bit fiddly.
Here's a link to the defender centre:
