Toolstation or screwfix do a full cistern for about 3 quid.
What problem are you getting? Not much to replace other than washers and diaphragm.
Well there are a couple of bits in there, the flush valve which is a small tube with a reservoir at the bottom of it, in the centre of the cistern usually, then there is the fill valve which fills the bog with water ready for flushing, this connects to the ball float which in turn stops the water when the cistern is full. Most likely just the flush valve is broken, if this is the case, you need to open the toilet up, take a picture of the flush valve assembly, then go to Screwfix or B&Q if you fancy getting robbed, pick one up. It is relatively easy but fiddly and you need to make sure the seal is right or you will get a leak.

Basically empty the toilet, undo the retaining nut under the toilet and the assembly should come out.
If the problem is that's its really hard to flush, or you have to 'pump' the handle then its likely to be the diaphragm in the siphon that has split.
Unless it is a 2 piece siphon that you can split apart, you will have to remove the cistern form the pan to change it.

Did mine a couple of weeks ago, and wasn't too hard.
