While I've always been happy with Redwolf (prefer eHobby though), I'm not sure why people are using shipping times as proof of their quality. Once the package is in the shipping company's hands, it's got absolutely nothing to do with the retailer. If the package took two days to get here, it's the shipping company you should be talking about. Now, the amount of time it takes them to get it TO the shipper..... that's something to discuss.
In addition, the shipper has pretty much zero control over customs. As long as they are putting on an orange tip and covering trademarks (which every HK retailer I've done business with does), then there's nothing else they can do. It's not like some retailers have a "Customs, don't look in this box" sticker.
