Can someone give me a run down of the different scuttles. I don't know what a SRD scuttle nor the GTP. Website links would be great. I've done a good amount of searching and have found the Moss, Dirtybird, Georgetown, and that huge German one, which I really want to get, I just dont have very much counter space, I'm going to find a way though. I still would like to explore all options. Thanks
