There is an upcoming 1,500 point tournament at WyvaCon in Wytheville, Virginia, on Saturday, July 26. This is the third year of the event, debuting in 2012 and continuing strong last year. Admission and registration is very affordable ($10 total I believe) and it sounds like a really good time.
The tournament will be a nice, streamlined 7th Edition take. Missions are only slightly adjusted BRB missions (Emperor's Will, Scouring/Big Guns, and Purge). The only restrictions are that armies must be battle forged, with a single primary and allied detachment allowed. You can find the current rules pack here.
It sounds like a great time and I wish I could make it, but it's not a good weekend personally. That said, if you're in the area, give it a look and head out for a good day of 40k.
