Hi Jonathan,
If you want a scope to last you the rest of your life and you can upgrade it as much as you want
Have a look at this

Not cheap, but i have looked through one and it is unreal so to speak
As i said buy this one and you don't ever need another one. keep the ETX as your grab and go scope.
My thoughts.
What ever you buy enjoy it.
