Sorry to hear that Big Fish, like others here I've only got basic security - locked doors, alarm, bikes chained. Do have the benefit of wife working from home so about most days and all 3 of my kids living at home and at the ages of coming and going at all hours and plenty of their mates around, not sure if I'll quite so secure in a few years time.
In 25 years never had a break-in of any kind so probably well overdue one, if and when it happens I hope I'm around to use 'self defence' on the scum, it's surprising how big a tyre lever I have for my push bike tyres >
