Try Edd at Panshanger, they have a Saratoga with a dodgy paint job(sun bleached Pink over white) but it is very reasonable @£188/wet all in!! Plus it is the retractable one with another 20kn cruise so you get where your'e going that much quicker. Plus if your'e going foreign it comes with a £150 cash back in the form of a duty draw back check from HMRC!! Now that has got to be worth it
Other ones to think of are G-BKEK at Turweston, although i hear it is up for sale! And Fowlmere have one at a reasonable(For Fowlmere!) rate!.
