You get a 3 year UK warranty with their kit. You send it to Sony in the UK and ******* pay the repair bill. Never had an issue with them.
No brainer, would definitely pay £200 more for another 2 years and you get a kit lens which you could probably claw back the £200 difference by selling (if you wanted to).
