I live in the UK so I can only get a Porter Cable by importing one for around $220 which includes shipping, import duty and tax added to the US price of around $130. After that I will have to get a 240 volt to 110 volt transformer to power it for about $100 making the total $320, and I still have to buy foam pads and polish. 
If I pay that and it breaks 2 months later I will be pretty unhappy. Trying to send it back to the US for repairs and then back to me would cost as much as you guys pay for a new one.
So, how long can I expect it to last if I detail my car 4 times a year ? Has anyone on this board ever broken one ?
