£30 suits at Asda/Tesco

For ppl looking around £80-100, if you are lucky enough to have a slater menswear near you check them out. They often have decent (as opposed to cheapo) suits within this sort of price range. Obviously you can go higher, but even given my extreme suit expertiese (errr) I think you're more likely to get a decent quality suit that you'll get a decent number of wears out of. http://www.slatermenswear.com/

Tried on one of the Tesco suits last year, only thing wrong with it was the trousers were a bit thin and clingy.

Ended up buying one from Burton, was £80 but we ended up getting 30% off so less than £60 for something a lot better quality.
