If you really want a Fender, I'd go for a new American Standard. £1100 or less if you haggle new. Solid basses, good hardware (the new bridges are fabulous) and they will do everything an old Fender will do, without the hassle of taking the neck off for truss adjustments or worrying about gigging a £3K vintage.
However, if you like you Stingray, and dig the ergonomics, (and this is coming from a Fender and Musicman fan) I would try out a few Musicman basses that have the neck pup.
E.g. Stingray HH/HS, Sterling HH/HS, Bongo HH/HS or the Big Al SSS (nails a P bass tone and a LOT more).
Not only will the Musicman give you a Fender flavour with the extra pups, you still get the Musicman tone/etc, ergonomics, and ease of setup.
