Steve, The clamp/plate system you are currently using is a proprietary design so you are stuck using their product. The Arca-Swiss type plates and clamps are more universal making the number of choices among different manufacturers much greater. There are many companies that offer Arca-Swiss type ballheads at affordable prices. You don't need to buy the big name/high priced items, but I believe it will be to your benefit to adopt the Arca-Swiss design. Serach the Net and you'll see how varied the prices are.
