Give it a couple days, there's lots that pop up on eBay and other places, plus I'm sure Massdrop will have them again soonas they are very popular. No reason you should have to pay more than 200 for them

Absolutely, they aren't too hard to drive, you almost get away without an amp but an E7 should have plenty of juice
