Recently there was a useful thread about cashmere from different shops. I think the general consensus was that some cheaper cashmere is good value for money but in general you get what you pay for.
However, i have a couole of jumpers from Brora and they do pill. One in particular has a more modern shape and looser knit and it pills really badly. On the other hand inalso have a very old cashmere jumper from Benetton (I think from the days when Benetton was still good quality) and it doesn't pill at all. Is it to do with how it's knitted?
