ideas of where to live near London

[sheffmummy]

DH has just got a new job meaning we need to relocate.
We'd prefer to live outside London (assuming it will be a little cheaper!) We'd also prefer to live north of London rather than south as it will be easier for visiting family. We thought about an hours commute to work is manageable. He will be based right next to Vauxhall so probably kings cross/ marylebone best. We just have one ds (nearly 2) so we'd like somewhere family friendly with good schools. Anyone any ideas? Thanks

What is your budget?

We are in Berkhamsted which is great for families but it is pricey.
