IsolationTank has lots of fun stuff at nice prices for more unusual bands; they've also always answered my emails quickly. In short, they are awesome, especially for having low prices on import CDs.
For what it's worth, their cheap compilation CDs are usually good, especially the Dancing in the Dark ones. (I have the 2007 Dancing in the Dark CD that included Carfax Abbey's "Love Hate Kind".)
(As it happens, they recently mailed me a VIP pass to Nocturne [an alternative music dance club they're tied to in Philadelphia, Pennsylvania], which I naturally had to decline due to distance issues [about a four hour drive?]. I'll also be in Arizona when The Crüxshadows are in Maine/New York.)
