I just got some for my boat but I got mine from Crappiekiller.com. They are adjustable both vert and horz. and sit up off the deck about 18 inches which is great of the back. I got extra bases so I can reposition them around the boat as well. Check out Crappiekiller.com, Mark posts on the TN board from time to time.
