DSA Laptop Warranty and InsuranceWatch
Try looking up DSA laptop insurance. My daughter found several providers last year and DSA reimbursed her for a 3 year policy with no problems. The normal computer suppliers insurance is not suitable- you need a specialist (the cover is much more comprehensive and expensive. DSA expects this)
I haven't done it yet because I haven't received my laptop yet, but my electronics supplier (Barry Bennett) actually has the option for you to directly go to their insurance partner's website to get insurance for your laptop at a 'competitive price' if you didn't go with the option get your laptop directly through them. Might be worth looking into!
