Anyone know of a LFS that carries Spectrapure DI's? Looking for the Super DI color changing (DI-SB-SI-10HC), but will take the non color changing. I can order online, but need to make some water soon and my Silica buster is expired (according to ICP) so I need to replace asap. I've called the most places in the valley, but may need to venture a little further from home?
