Chriusta, it is always wonderful when you can get fresh fruit to juice.  Most times I am able to do that.  With the exception of grape juice.  I love Concord grapes, but never have access to enough of them.  I have made grape jelly many times with bottled grape juice.  It comes out wonderful and it does save a lot of work.  I don't know about other juices you mentioned.  It is best when you can have your own fruit or fruit is given to you, then it is free except for the sugar, etc.  In canning I don't count the labor, just know that when winter comes it is all worth the effort.
