hiya snotty!
welcome aboard
for $400 you could get a much bigger telescope like a 150mm or 200mm dobsonian mounted newt. it woud be more stable than what you have given us to choose from and you will see a hell of alot more
generally speaking the more aperture the more light gathering ability you get the more you can see.
theres a shop called andrews communications that has the scope i mentioned as does bintel and myastroshop.
hopethis helps.
