The Contour Racks are great and can be filled w/ lead shot or sand (I use shot which is much easier to fill). I have had great success with my Contour rack using Sumposium isolation bases. Plus the Contour stuff looks great. I would also highly recommend the StudioTech speaker stands. I am currently using their "hifi series" which are identical to the Target R series stands. The StudioTech's retail for $300 and the Target's retail around $650. Good Luck...
