I got mine from Jab-tech yesterday. My only complaints: It didn't come with instructions or the required tubing. Small annoyances, really, but the instructions really would have been handy for showing the correct way to install the rivets. The rest of my system uses 3/8" ID tubing, so getting the 1/2" ID tubing required for the stackable meant making a late night run to Home Depot. I really don't like to buy products that don't include *everything* you need to use and/or install the product in the box. Even if you have to bump the price up a buck or two, it would be very nice to have about three inches of 1/2" ID tubing included with the rad.
