Not sure about Neck Thru - But what you specified is the spec for pretty much every ESP.
Check them out if you can - The M-2 is a superb guitar although the neck may be a bit thick.
If you're open to different woods I would DEFINETLY look at Caparison.
The Dellinger and TAT are 24 fret - While the Horus is 27 fret and H-S.
All have been incredibly well aclaimed - And definetly on my wishlist atm.
Those are my options for 1000-1600 mark dream guitar style things.
For the £800ish market I'd say LTD M1000 - Neck thru but a rosewood fretboard - Then again, most guitars in this pricerange are.
MANY will disagree - But it really is a superb guitar.
My Ibanez RGT42DXFM is also pretty freaking amazing - Mahogany body, flamed maple top, neck thru, maple/walnut neck, rosewood fretboard and a locking trem. Fantastic guitar, although the trem may need replacing.
