Only bought one small item off Dave- a headset spacer. It never showed up. He did offer me a refund, I said I'd wait a bit longer for it first (Australia Post are just as efficent as Royal Mail, so when a package goes through both it could well get a bit lost). It's been nearly another week so I was going to get in contact with him again but since he's gone (and since it not showing up may not be his fault) I'll write it off. No big loss.
More to the point, what about people like Defiant? Was the frame postage issue resolved mate?
