For very light compact cameras, there are two realistic alternatives mentioned:

1. DIY stabilizers: A homemade counterweight/gimbal-style stabilizer can be a practical low-cost option. Many DIY tutorials exist, and you can scale the design down for a small point-and-shoot.

2. Modern handheld gimbals: Electronic 3-axis handheld gimbals have become a lighter, more affordable alternative to older professional stabilizer systems. The key is to choose one rated for your camera’s size and weight.

A simple grip is not the same thing as a stabilizer—it may improve handling, but it will not provide the smoothing effect of a true gimbal or balanced stabilizer.

So if budget is the main issue, a DIY rig is likely the cheapest route; if you want convenience and better stabilization, look for a lightweight handheld gimbal compatible with compact cameras.
