I've owned both saws and wouldn't hesitate for a second to say go for the 260 if you can swing the extra $. It's well worth it.
If you plan on keeping the saw for a while, sooner or later something will break and the 260 is a joy to work on compared to the 270.
I'd never buy anything in the 1123 or 1133 series again.
If you happen to have any 1123 series sitting around send them my way.
I love those stupid little saws.
