Hi June,
I know full well what you are going through at the moment.
Saving very hard indeed for that first scope.
I'd like to advise against a scope on an EQ mount.
A Dobsonian mounted scope would be perfect. It's a very simple design, so simple that your 6yr old will be using it in no time.
You would probably be quite happy with a 6" $349 or an 8" $399 size mirror.

They're great value for money.
