Patience first James. Bigger apperture will give you better views, but sometimes a better quality eyepiece will give an equally improved view.
I suppose it just depends on how deep your pockets are.
Another consideration is, are you expecting to see the item bigger than is actually possible.
Viewing conditions, such as light polution, temperature etc will also have an affect on what you are viewing.
Learn to locate the various objects you wish to view, experiment with the different eyepieces available to you. Then move forward from there.
Good luck with your viewing, there is so much to see.
