Morty, if you find such a place keep it quiet or we'll all be coming to ruin the neighbourhood!
Herself and I never regret giving up commuting 15 years ago (quality of life is so much better) though we couldn't afford to move to where we are if we were doing it today, but moved when our previous house in North London had appreciated at a ridiculous rate (they knocked down our very cheaply rented place in South London ten years earlier to build a slum!),and the People's Republic of Bracknell Forest is not near the sea!
The trouble with the places that are affordable is usually that there are no jobs to help you afford them!
Then again the nice places scenically,especially by the sea, are also expensive unless too remote for all but helicopter owners!
I sometimes hanker after the Somerset/Dorset border area if the Lottery comes up trumps but we'd probably stay put but buy one of the obscenely expensive places near here with a pool and room for a Mudgathering instead!
But best of luck in your search!
