I agree with boogalloo.

Both are useful devices, both would be worthwhile additions to your tool kit, but the deflection meter can wait. I feel, however, that the CG machine is important.

While the other suggestions about fingers, custom stands, etc., undoubtedly work, the Great Plane CG Machine is an ingenious gadget that gives you a pretty precise idea just where your model's center of gravity is. If you wish, you can get by by with the TLAR method and fingers.

Proper balance is quite important. It can mean the difference between a model that flies great or like a pig.
