Cheapest OBD2 coilpack suppliers?

[The Monk 50]

Trying to find the cheapest coilpacks that I can. Bosch happen to sit at £109.59p and I cant afford that....well, I can, but I'm selling the car and I don't want to go spending £100's for the coil pack and HT leads to sell the bugger.

Any idea who sell the cheapest but with a compromise to the reliability?... I want to sell but do not want the next owner being screwed over (because I'm good like that).

Cheers in advance.
