New timing belt kit 200tdi

I want to fit a new timing belt kit in my 200tdi that i put in my 90, the engine is out of my first disco 1, i changed it a few years ago with all the best stuff from a landrover dealership, that was 85k ago!!!! when the lot cost around £50 quid. Does anyone know where i'll get the best deal now without buying crap stuff for the whole lot, (belt, gaskets, idler, tensioner, and crank seal)
All advise appreciated....

Go to a factors and get a GATES kit or something like that, they are all decent really, unless you go to dodgy jims chinese parts emporium

I used mailorder4x4. Same belt as the OE jobby and (what look like) decent quality ancillaries. Cannot remember how much off hand but it's on their website.
