Yes, they've been recommended before and I've found them to have all sorts of great things - I bought thirty spire clips for the rear lights from them last month and they worked a treat.
I actually went out today, limited myself to an hour as I'm getting garage fatigue from struggling with the same jobs day after day for up to eight or even ten hours throughout the course of the day, and the other trim fitted first time. So did the speaker, which had refused to line up with the mounting holes for days now, so I think the car is getting the message: work with me, or you can sit in a dark garage and think about what you did wrong.
