Fair comment. The overlever of the Gamo is plastic, but it is well chosen and well up to the job.
The Baikal will last you a lifetime, but i would warn you again, it is heavy, at about 3lb. If you are happy with 3lb hanging on the end of your arm, I'm sure you won't regret your choice.
If you got a s/h Gamo whilst waiting for a baikal to turn up, the chances are you wouldn't lose a penny and you'd be up and running straight away.
Good luck whichever way you go.
