If you don't do much tabletop work, a good levelling head may suffice. Even my smaller one (made by Linhof, and at least 40 years old) easily carries a light 8x10 camera. This head weighs only 180 gram, but its cut-off ball is almost as big as the Arca Swiss Magic Ball's diameter. +/- 15 movement is enough for most landscapes and portraits, and relieves from fears to topple the camera. One might say, this is no substitute for a "real" tripod head. But if you have been using one, you may well think otherwise.
