I think you're right DD, still, for the cost it's a great scope.
Great to hear you've order one Frosty.. the 4mm EP will be good for planetary and lunar detail, but will require better than average seeing to make the best use of it, and things can get pretty dim in those short focal lengths.
I got a 9mm, and with a 2x barlow gives me a 4.5mm, so you basically double your EP set with the use of the barlow, so it's best to choose the focal lengths that allow the barlow to be used to get the in-between focal lengths.
The 30mm will be good, it's a good low-medium magnification and will be great on deepspace objects, as well as full disc views of the moon.
Did you get to choose another 2 EP's?
You should try the binoculars more often, it's amazing the detail you can see, the expanse of stars and faint fuzzies that pop out.
Good luck and keep us posted!
