Thanks to my Kindle I have recently been reading Robert Rankin. His books are wonderfully funny, with a great bit of Terry Pratchett-esque colloquialism - all very down to earth, but with beautiful flights of fancy too.
I have read 1 book previously (the Hollow Chocolate Bunnies of the Apocalypse - fabulous) and these two - Necrophenia and Japanese Devil Fish Girl were on my Kindle.
The newest (Japanese Devil Fish Girl) is the best of the latest two - truly a writer improving with age!
I would definitely read all of his books. Easy to read, great comedy and very cleverly insightful!
