As yet I have only purchased, not attempted a build. I can see it in my future though. The first two cams were Sony P41's with Snapshotsniper boards and I paid $350.00 each. Picked up two more of the same in the early spring for $225.00 each. It was the offseason and got a better price. The last two are S600 Sonys with Yeti control boards. Actually the pics are a little clearer, and paid $160.00 for the first, and $140.00 for the second. All are whiteflash homebrews.
